Hey guys i have a problem with the NonRetryableError thing. I have the following code

step.do('Validate params', async () => {
            if (!event.payload.email) {
                throw new NonRetryableError('No email provided');
            }
            if (!event.payload.url) {
                throw new NonRetryableError('No url provided');
            }
            if (!isValidUrl(event.payload.url)) {
                throw new NonRetryableError('Invalid URL');
            }
            if (!isValidEmail(event.payload.email)) {
                throw new NonRetryableError('Invalid email provided');
            }
        });

step.do('Validate params', async () => {

                throw new NonRetryableError('Invalid URL');
            }
            if (!isValidEmail(event.payload.email)) {
                throw new NonRetryableError('Invalid email provided');
            }
        });

            if (!event.payload.email) {

            }
            if (!event.payload.url) {
                throw new NonRetryableError('No url provided');
            }
            if (!isValidUrl(event.payload.url)) {
                throw new NonRetryableError('Invalid URL');
            }
            if (!isValidEmail(event.payload.email)) {
                throw new NonRetryableError('Invalid email provided');
            }
        });

step.do('Validate params', async () => {
            if (!event.payload.email) {
                throw new NonRetryableError('No email provided');
            }
            if (!event.payload.url) {
                throw new NonRetryableError('No url provided');
            }
            if (!isValidUrl(event.payload.url)) {
                throw new NonRetryableError('Invalid URL');
            }
            if (!isValidEmail(event.payload.email)) {
                throw new NonRetryableError('Invalid email provided');
            }
        });

and everything is fine until the error gets thrown and the workflow doesn't stop there but instead executes all other steps as shown in the screenshot.
Does anyone have the same problem or is it just a skill issue on my end?

It's not possible to "dynamically spawn" steps in a one-to-many relation, right?

I've been thinking about an use-case, where I want to send out weekly report e-mails.

The most safe way of building this without risking double sends, would (I think) be to have one starting-step in the workflow that queries all users that should receive an report, and then I would want to spawn a further step/task for each user where the personalized report is generated and sent.

This is (currently) not possible with a workflow alone, right? I would need to use a queue instead

I would if I were you store the emails you need to send in a KV or any other temporary storage from cloudflare, do that in a seperate step, and then in the next step first check if you've already sent it to that email, then send the email, then mark it as send in storage all in the same step. This makes it idempodent. Then in the final step do a clean up for the storage.

What's the best way to implement "wait until signal" on userland? sleeping and pulling?

A

Ashley•2/11/25, 7:56 PM

Do you mean the user (browser) polling to check if the Workflow has finished, or the Workflow waiting for “something” to happen?

F

Focux•2/11/25, 8:10 PM

I mean something like this:

while (true) {
  const isDone = await checkIfSomethingIsDone()
  if (isDone) break;
  step.sleep('wait for event', '5 minutes');
}

while (true) {
  const isDone = await checkIfSomethingIsDone()
  if (isDone) break;
  step.sleep('wait for event', '5 minutes');
}

while (true) {
  const isDone = await checkIfSomethingIsDone()
  if (isDone) break;
  step.sleep('wait for event', '5 minutes');

Figuring out the right interval would be tricky in my case. I have a workflow that has several steps, and one of those is sending an email. I want to wait for that email to be opened before continuing with the workflow execution.

A

Ashley•2/11/25, 8:39 PM

Yeah, there’s no native way to do this yet (maybe it will come later - it seems a no brainer to me) so I think a repeated sleep is the only way

You could as the workflow ID is available inside the Workflow class, you’d then call resume I believe on it (using Workflow binding for example)

For sleeping workflows, I think I saw that they don’t contribute to the concurrent count, but is there a “minimum” sleep before this is true?

S

Seekerdasbatatas•2/12/25, 2:14 PM

the minimum sleep required atm to pass it to waiting is in the minutes range (and the transition happens after that time has passed) - so I don't know if it's worthwhile hacking around that. I've personally seen people pausing and resuming an instance to "emulate" events, but on a lighter note, we're working on native events :soontm:

A

Ashley•2/12/25, 2:22 PM

The use case is let’s say it takes 10-30 seconds for something to happen, I don’t want to sleep for say 45 (to be safe) or “poll” at 10 seconds or it would eat concurrency. I could set it to 5 mins, let’s say, but then there’s an unneccessary gap. I have a little solution using a DO (pause workflow -> call DO that sets alarm that effectively does the polling -> DO resumes workflow when event happens) and it works nicely until native events, but wondered if it was worthwhile (but if it’s minutes, I think so for now)

Seekerdasbatatas•2/12/25, 2:25 PM

Considering that you probably don't have stuff running parallel to the wait for event call, that seems to work nicely

A

Ashley•2/12/25, 2:28 PM

Yeah, what would have been super cool was if I could define the callback (well, the logic to determine if to continue) in the Workflow and pass it to the DO, but alas the “connection” doesn’t naturally survive hibernation

https://github.com/apeacock1991/workflows-wait-for-action/ this was surprisingly easy (I wrote it at the weekend, hadn't had the time to check if it was useful until just then) for anyone that wants to pause/resume workflow using a DO and "protect" your concurrency limit

wesbos•2/12/25, 6:15 PM

Hi folks - having some trouble with throwing errors inside a workflow.

First, it seems throwing a NonRetryableError, is retried as many times as specified

Second, I can't seem to find out where the throw error messages are being returned in the workflow status. The docs seem to say

const wf = await MY_WORKFLOW.get(id)

const wf = await MY_WORKFLOW.get(id)

and then

await wf.status()

await wf.status()

should return errors, but they are always empty.

here is the code I'm using to reproduce:

export class MyWorkflow extends WorkflowEntrypoint<Env, Params> {
    async run(event: WorkflowEvent<Params>, step: WorkflowStep) {
        step.do('Step 1', async () => { return 'Step 1 finished!';  });

        step.do('Step 2', {
            retries: { limit: 2, delay: '1 second', backoff: 'linear', },
        }, async () => {
            console.log('Trying Step 2');
            throw new NonRetryableError('Step 3 failed. Non-retryable');
        });
    }
}

export class MyWorkflow extends WorkflowEntrypoint<Env, Params> {
    async run(event: WorkflowEvent<Params>, step: WorkflowStep) {
        step.do('Step 1', async () => { return 'Step 1 finished!';  });

        step.do('Step 2', {
            retries: { limit: 2, delay: '1 second', backoff: 'linear', },
        }, async () => {
            console.log('Trying Step 2');
            throw new NonRetryableError('Step 3 failed. Non-retryable');
        });
    }
}

export class MyWorkflow extends WorkflowEntrypoint<Env, Params> {
    async run(event: WorkflowEvent<Params>, step: WorkflowStep) {
        step.do('Step 1', async () => { return 'Step 1 finished!';  });

        step.do('Step 2', {
            retries: { limit: 2, delay: '1 second', backoff: 'linear', },
        }, async () => {
            console.log('Trying Step 2');
            throw new NonRetryableError('Step 3 failed. Non-retryable');
        });
    }
}

export class MyWorkflow extends WorkflowEntrypoint<Env, Params> {
    async run(event: WorkflowEvent<Params>, step: WorkflowStep) {
        step.do('Step 1', async () => { return 'Step 1 finished!';  });

        step.do('Step 2', {
            retries: { limit: 2, delay: '1 second', backoff: 'linear', },
        }, async () => {
            console.log('Trying Step 2');
            throw new NonRetryableError('Step 3 failed. Non-retryable');
        });
    }
}

This logs "trying step 2" three times

You cannot rely on the garbage collector for this because it may take arbitrarily long before actually collecting unreachable objects.

I see that

step.do

step.do

expects to return

, so I did a little bit of reading about the RPC lifecycle here and found that in the context of Worker Service Bindings, you should either use the experimental

using

syntax, or explicitly call

object[Symbol.dispose]()

.

I'm a little confused because this error is only thrown after some calls to

step.do

step.do

, and not others. If someone could provide some insight as to what's going on, that would be great. Happy to provide more details also

can anyone help me understand the cost difference of a workflow, while the workflow is running does this add all cpu time during the total run time or just during events that trigger CPU time effectively making the cost that same as using wokers native or roughly the same

I'm curious for scale if I implemented in two ways

Option 1. I send post req with a worker webhook url and then when the job is completed webhook is hit generating new worker instance to handle post job completion duties

Option 2. I create a workflow that for a particular "generation" or request tracks/handles everything, initial http post req as well as waiting for job completion

can someone confirms AsyncLocalStorage will not behave as expected in a step fn unless the callback is defined inline ?

async run(event: WorkflowEvent<Params>, step: WorkflowStep) {
    await context.run({ id: "124" }, async () => {
    // loadFile will get undefined when calling content.getStore()  
    const txt = await step.do("load", loadFile);
    const txt2 = await step.do("load2", 
// this one will work
async()=>console.log(context.getStore().id));
    });
  }

async run(event: WorkflowEvent<Params>, step: WorkflowStep) {
    await context.run({ id: "124" }, async () => {
    // loadFile will get undefined when calling content.getStore()  
    const txt = await step.do("load", loadFile);
    const txt2 = await step.do("load2",

async()=>console.log(context.getStore().id));
    });
  }

Question: has anyone encountered problems doing image transforms in workflows? I'm encountering a strange issue where my image transformations aren't working at all.

I have a pretty basic request, fetching an image from an external domain. I can confirm that the

Cf-Resized

Cf-Resized

header is

null

null

and the

Content-Type

Content-Type

header is un-changed (

image/jpeg

image/jpeg

).

    const image = await fetch(imageUrl, {
        cf: {
            image: {
                format: "webp",
            },
        },
    });

    console.log(
        "Image headers, post-transform",
        image.headers.get("Cf-Resized"),
        image.headers.get("Content-Type"),
    );

    const image = await fetch(imageUrl, {
        cf: {
            image: {
                format: "webp",
            },
        },
    });

    console.log(
        "Image headers, post-transform",
        image.headers.get("Cf-Resized"),
        image.headers.get("Content-Type"),
    );

    const image = await fetch(imageUrl, {
        cf: {
            image: {
                format: "webp",
            },
        },
    });

    console.log(
        "Image headers, post-transform",
        image.headers.get("Cf-Resized"),
        image.headers.get("Content-Type"),
    );

    const image = await fetch(imageUrl, {
        cf: {
            image: {
                format: "webp",
            },
        },
    });

    console.log(
        "Image headers, post-transform",
        image.headers.get("Cf-Resized"),
        image.headers.get("Content-Type"),
    );

I'm calling this from within a Workflow, in case that matters. I do have Image Transformation enabled for the zone in which the worker is running. I'm not running this on a

worker.dev

worker.dev

domain, this is in the expected zone (but on a sub-domain). I have confirmed that Image Transformations are working with another worker within the same zone, so the only thing difference is the use of a Workflow. Is there something that I'm missing here? Thanks!

Unsmart•2/20/25, 7:01 PM

It's not possible for a workflow to run on a custom zone it will always run as if in the "workers.dev" zone. So I don't think it's possible to use image transforms through workflows unless they made it possible to use transforms in workers regardless of zone since I last checked.,

John Resig•2/20/25, 7:03 PM

Oh interesting - that's very helpful, thank you! This makes me wonder if I could make another worker in the right zone and use service bindings to talk with it?

But the metrics dashboard already shows 425 new processed workflows!
