it might be my own fault but whilst I've been loving the capabilities of workflows (and they might just be my fav new primitive) – last night it's been the 2nd time I've been running into issues troubleshooting errors whilst developing them (once deployed).

unless last night there were some internal issues?

Is it possible to extend the NonRetryableError into a custom error while maintining it's workflow ending power? Because this doesn't seem to work:

class EndWorkflowError extends NonRetryableError {
    event: WorkflowEvent<Params>;
    shouldFallback: boolean;

    constructor(data: {
        message: string;
        error: unknown;
        event: WorkflowEvent<Params>;
        shouldFallback?: boolean;
    }) {
        super(data.message);
        this.name = 'EndWorkflowError';
        this.message = data.message;
        this.event = data.event;
        this.cause = data.error;
        this.shouldFallback = data.shouldFallback === undefined ? true : data.shouldFallback;
    }
}

    event: WorkflowEvent<Params>;

        shouldFallback?: boolean;
    }) {

        this.name = 'EndWorkflowError';
        this.message = data.message;
        this.event = data.event;

S

Seekerdasbatatas•4/4/25, 12:57 PM

my recommendation is always the latter, you shouldn't expose Cloudflare API tokens directly to users and instead maybe create your own (maybe by using auth providers, like clerk and so on) - so that you can also have proper validation in your endpoints too

M

Matt Silverlock•4/4/25, 1:40 PM

Strongly agree here. If you need client side authentication, use a library or tooling that’s appropriate for that + gives you the controls that allow you to scope access precisely

M

Matt Silverlock•4/4/25, 1:41 PM

That will also allow you rate limit clients, emit metrics to Analytics Engine, validate payloads, etc - before they hit the workflow

M

Marc•4/4/25, 3:10 PM

Suddenly whenever my worker invokes my workflow I am getting a 500 error (Error: internal error {} )

I've tried looking all over for a better error log to explain what's going on but so far can't get it to tell me. If I wrap the workflow create call in a try catch all I get is the above error.

My only slight lead is that maybe this started to happen after I tried to cross script bind the workflow to another worker, but that's not the script I'm calling this one from. Could a bad binding to something else be messing up this binding?

Any leads on where to get a better error message on what's wrong or is there something going on with workflows?

J

Justin•4/4/25, 8:24 PM

What's the best practice for making a workflow step conditional?

Like, can I do the following to skip a step entirely?

const shouldHappen = await step.do('check condition', async () => { return false })
if (shouldHappen) {
  await step.do('conditional step', async () => { //do something })
}

const shouldHappen = await step.do('check condition', async () => { return false })
if (shouldHappen) {
  await step.do('conditional step', async () => { //do something })
}

const shouldHappen = await step.do('check condition', async () => { return false })
if (shouldHappen) {
  await step.do('conditional step', async () => { //do something })
}

const shouldHappen = await step.do('check condition', async () => { return false })
if (shouldHappen) {
  await step.do('conditional step', async () => { //do something })
}

Or, should I evaluate the condition within a step, like this?

const shouldHappen = await step.do('check condition', async () => { return false })
await step.do('conditional step', async () => {
  if (!shouldHappen) return
  //do something
})

const shouldHappen = await step.do('check condition', async () => { return false })
await step.do('conditional step', async () => {
  if (!shouldHappen) return
  //do something
})

const shouldHappen = await step.do('check condition', async () => { return false })
await step.do('conditional step', async () => {
  if (!shouldHappen) return
  //do something
})

const shouldHappen = await step.do('check condition', async () => { return false })
await step.do('conditional step', async () => {
  if (!shouldHappen) return
  //do something
})

Matt Silverlock•4/5/25, 12:53 PM

I like to say: Workflows are just code. Call steps conditionally, use Promise.all or p-map or (etc) to run steps concurrently.

step methods are just async function calls at the end of the day.

dragonli•4/6/25, 12:27 AM

Is there anyone who knows how to make the workflow execute immediately?

I found that there seems to be a delay between triggering the creation of a workflow from a worker and the actual execution of the workflow.

According to the test, it is close to 4 or 5 seconds. How can I make the workflow execute immediately?

D

dragonli•4/6/25, 12:31 AM

Currently, I'm triggering workflows via webhooks and want them to execute as quickly as possible. Should I switch to long-polling an API within the workflow instead? Is this usage considered a best practice?

K

Kiwi•4/6/25, 3:54 AM

I'm also seeing this from my RPC call to workflow spin up being quite slow. It is so slow that I'm actually going to bring that code back into my request flow as it will be on the whole quicker.

M

Matt Silverlock•4/7/25, 11:01 AM

What do you define as slow here? Workflows are designed for async tasks, so if you’re trying to run something that only takes a few seconds it may not make sense. But the Workflow itself should fire off quickly, provided you aren’t at concurrency limits.
