We are having an issue where one of our workflows starts failing every single instance whenever a CF build runs on a completely separate (unrelated) worker. It keeps failing until we trigger a re-build on the workflow's worker. This is an extremely annoying issue and very unclear why this would even be happening.....

Alec•8/7/25, 7:59 PM

Hi, any workflows we create are giving off a Internal Server ErrorInternal Server Error, and we can't view our Workflows in the dashboard. Any incidents going on?

JHT•8/9/25, 7:11 AM

Hey fine people, I have a quick question about the new Sentry logger (https://develop.sentry.dev/sdk/telemetry/logs/).

Logs sent from my regular workers are appearing in Sentry perfectly. However, any logs triggered from within my workflows are not being received at all.

Is there a known issue or a different configuration required for logs coming from a workflow environment?

fforres•8/9/25, 3:23 PM

We have a ton of workflows in our dashboard and We handle two environments on the same account.
So we end up having:

long-workflow-name
long-workflow-name-stagingIs there any way that we can have tags or anything that will help us find workflows easier? maybe a filter tied to the URL? So i can save search urls for example? Maybe sorting the workflow table could also be useful.

Brandon•8/9/25, 10:16 PM

Hey @fforres we recently introduced this to the d1 table we can look at bringing in a similar pattern for workflows as well!

The last step on one of our workflows is to batch send a newsletter to many users. We really don't want it to retry, ever. Locally, I had added a config of {retries:{limit:0}}{retries:{limit:0}} to the step, but wrangler deploywrangler deploy didn't like that one when releasing to prod. So I wrapped the function with a try/catch throw new NonRetryableError()try/catch throw new NonRetryableError() and hoped for the best. Unfortunately, we've already had our first double send. The batch send step failed with a Attempt failed due to internal workflows errorAttempt failed due to internal workflows error, which seems to skip/miss the try/catch, so the (already successful, but now timed out) step retried

I'm going to add a KV check to the start of the step, but am I missing something super obvious? Is there a recommended pathway for getting a step to only ever run once?

Matthias•8/12/25, 5:06 AM

In terms of UX, that would be great to reassure end user about the processing of each step, totally agree. Do we have to use the api and not the workers binding? Also, I'm noticing in local env that error is not returned from the instance status, but returned in the production env which make it really hard to test it out.

await new Promise(resolve => setTimeout(resolve, 1000));

p.s. I know there is step.sleep, but little bit concerned to use it within a loop to exceed max number of steps.

nachotoday•8/14/25, 2:54 PM

It doesn’t look like there’s a way to run cleanup if I call terminate — is that right? So if I want to have a cancelable workflow that can cleanup or rollback steps, I have to do some hacky stuff with waitForEvent (like using Promise.race and making all my step promises cancelable).

At that point maybe it’s better to have a cancel workflow with a step that calls terminate on the actual workflow, then runs cleanup (and the real workflow share progress out of band so the cancel workflow knows what to do, eg recording to a DO)?

hmnd•8/18/25, 5:58 AM

@Luís Duarte

sorry for the ping, but would really love to know your thoughts on this. It would be great to have the ability to handle fatal errors at the workflow level, rather than having to handle each step individually.

hmnd•8/18/25, 6:12 AM

For everyone here annoyed by the cumbersome nature of try catching on every step, particularly when you need to use the result of one step in another, remember that because step.dostep.do returns a promise, you can use .catch().catch() on it!

const validationResult = await step
  .do('validate', async () => {
    // do some logic here
    return { somedata: true };
  })
  .catch((e) => {
    // handle your error here, and possibly re-throw it if you want it to be fatal
  });

const validationResult = await step
  .do('validate', async () => {
    // do some logic here
    return { somedata: true };
  })
  .catch((e) => {
    // handle your error here, and possibly re-throw it if you want it to be fatal
  });

Or if you are already using neverthrowneverthrow in your project like I am, you can do this!

const validationResult = await fromPromise(
  step.do('validate', async () => {
    //  do some logic that could throw here
    return { somedata: true };
  }),
  (e) => e,
).match(
  (result) => result,
  (e) => {
    // handle your error here, and possibly re-throw it if you want it to be fatal
  },
);

const validationResult = await fromPromise(
  step.do('validate', async () => {
    //  do some logic that could throw here
    return { somedata: true };
  }),
  (e) => e,
).match(
  (result) => result,
  (e) => {
    // handle your error here, and possibly re-throw it if you want it to be fatal
  },
);

tornado•8/18/25, 11:34 PM

was there any recent change to workflow subrequests limit? I'm suddenly seeing some workflows failing with "too many subrequests", this seem to even effect other steps. For example I have a try catch on every step to make sure I update the task status in my db to failed but that fails too because cloudflare isn't allowing the requests (erroring with "too many subrequests") even in different steps

tornado•8/18/25, 11:49 PM

I have 2 workflows (since closed beta) that have now accumulated over a million of finished (combo of succeeded, errored, and terminated). The backing DO of the workflow itself seems to really struggle (many times getting timed out) just loading instances on the dashboard. And it seems to be ignoring the retention limit

I still have workflows and their full step details (some had bugged code that caused thousands of retries on steps) from 6 months ago. Could someone help "cull" some?

Hey all we just added support for python workflows

They are still in beta, but would love to get your thoughts, what kind of templates would you like to see, what would you want to build on top of Python workflows?

Here are the docs: https://developers.cloudflare.com/workflows/python/

Please let me know if you need any additional information to get started building, or if there's any clarity I can help provide.

Happy shipping!

Also — fun fact, some of you who are more avid workflow users with lots of resources should hopefully notice a decent performance boost in the dashboard/api.

ALECKS•8/27/25, 3:29 PM

is there an quick / easy way to run a workflow locally real quick, I think I saw that the normal CLI does not work locally. Or do I need to add a fetc() api to the workflow and invoke it that way?

Devoto•8/27/25, 10:31 PM

Hi there, so I was checking the:

https://developers.cloudflare.com/workflows/reference/limits/

And noticed it says:

Maximum Workflow instance creation rate 100 per 10 seconds

Is this the env.MY_WORKFLOW.create()env.MY_WORKFLOW.create() call? If so, let's say after user registration, we want to setup billings, welcome emails, etc for the user (our most common use-case currently), with our usual load, we would that limit incredibly quickly, what is the solution for these scenarios?

does a workflow count as a single worker invocation for the purpose of worker sub requests?

Levi•8/29/25, 4:03 PM

I'm retrieving topK from KV in one step, and returning it as state to use in the next step. When I return topK from the step where I retrieve it, the type is number. When I try to use it in the next step where I query a vectorize database, it's a string. So, it seems like it serializes my number as a string between steps. Is that intended behavior?

The vectorize query requires topK be a number and I thought I was passing it a number.
