also interested in this. huge impact on design decisions (and frankly whether workflow fits many use cases or we need to stick to good ol' temporal)

Tory•7/26/25, 5:27 PM

We started seeing this error yesterday in one of our workflows

The RPC receiver does not implement the method "run"

The RPC receiver does not implement the method "run"

. It seems to happen randomly after a successful build of the worker. The only thing that fixes it is re-running the build.

Has anyone else seen this recently?

surgery18•7/28/25, 8:20 PM

I have a step in a workflow that could take multiple minutes to run (Google Gemini API call generating TTS of a script), it keeps hitting 100 seconds and then errors out. Any way to fix that?

surgery18•7/28/25, 8:25 PM

The step returns this

ApiError: {"error":{"message":"error code: 524","code":524,"status":""}}

ApiError: {"error":{"message":"error code: 524","code":524,"status":""}}

which is a timeout error. I am guessing steps have a limit of 100 seconds and then kills the network call. Any way to have the step last as long as the network call lasts?

Ssurgery18 The step returns this `ApiError: {"error":{"message":"error code: 524","code":52...

Chaika•7/29/25, 12:11 AM

That sounds more like the generic proxy limit then Workflows itself.
Cloudflare as a cdn/proxy has a 100 second read timeout which will respond with a 524 if you exceed it: https://developers.cloudflare.com/support/troubleshooting/http-status-codes/cloudflare-5xx-errors/error-524/.
If the body starts responding/streaming you can get around this, or maybe the Gemini API has a different way to poll for updates. Normally you can also raise this if you are Enterprise as well but since Workflows don't run on a specific website, might be difficult.

surgery18•7/29/25, 12:15 AM

Hmmm...Ok. I will see if Gemini API has a streaming option. Probably does. I will try that then. Thanks.

Brandon•7/29/25, 4:27 PM

Hey apologies on the delay here, we are actively working on upping the concurrency limits on workflows, this will be shipping in the near future and I can provide more details as we get closer to going live with it.

hype•7/31/25, 11:10 AM

Do workflows also share same connection limits that DO/worker has? As in you cannot do more than 6 fetch calls simultaneously?

Developres•7/31/25, 11:11 AM

Hello everyone, I want to use cdn. I haven't used it on my website before. How do I use it? Can you send me a video?

hype•7/31/25, 7:50 PM

Is there a limit on how long a workflow can run?

hype•7/31/25, 7:50 PM

Can it have infinitely long running task on it? How long each step can run for?

Cristian Lipinski•8/1/25, 10:16 AM

Hello guys,

since yesterday (2025-07-31) my workflow instances started by "createBatch" are not using my defined id, as the documentation says:

// Create a new batch of 3 Workflow instances, each with its own ID and pass params to the Workflow instances
const listOfInstances = [
{ id: "id-abc123", params: { "hello": "world-0" } },
{ id: "id-def456", params: { "hello": "world-1" } },
{ id: "id-ghi789", params: { "hello": "world-2" } }
];
let instances = await env.MY_WORKFLOW.createBatch(listOfInstances);

its creating its own id as if we were creating it without passing the parameter, we have dozens of workflows so it does not seen like a isolated thing

could anyone help me with that? thanks

Cristian Lipinski•8/1/25, 10:29 AM

I would also like to report another problem that we're seeing in some workflow instances, our account has multiple domains, we have some workflows that make some on more than a hundred domains once by day

some of my instances, although it completes all steps, are returning "with error" status, for example, the instance ID: 0ec749d5-fdb9-4dbd-b8da-b1a03bf4ca2e

toxec•8/1/25, 5:58 PM

Hello, what’s the easiest way to manually trigger a workflow in a local environment? I know I can’t just use wrangler, so my current workaround is to set up local-only routes and invoke them with curl, but it doesn’t feel ideal. I’m using Hono with Vite.

Cristian Lipinski•8/4/25, 1:21 PM

Hello there guys.

We're passing though really tough loading problems on my companies main account, all our GUI is way too slow, im uploading some examples on what we are experiencing

we work with 4 cf accounts, and only on our main account, that has hundreds of workflows, workers, kv, d1 is passing through all those loading problems

beside the loading, we're also havind a hard time deploying our workers, im also uploading examples

lastly, some of our workflows, even using "createBatch" are failing, with "Internal error"

What should we do about that? Maybe spliting our routines on other accounts? Is there anything to do in order to increase our performance?

Please let me know if there's anything we could do, we really like most of CF services, but as we're scaling, its not working as we expect.

we're even considering options like trigger.dev, its really frustrating because we really love CF, but if we can't trust it on high numbers,its hard to keep working with it

fforres•8/4/25, 9:38 PM

Hey folks

Saw that the column sorting on the workflow list page is not working properly.

Seems to sort by some logic, but not by date value or retries, etc.

fforres•8/4/25, 9:39 PM

here by retries or cpu time

Brandon•8/4/25, 11:21 PM

King Kazu•8/6/25, 4:45 PM

is there any plans to add a cleaner way of error handling that isn't try-catching everything? I just need to call a function to update my db with failure state, and having something as simple as

{ step-failed: 'blah-blah', timestamp: '' }

{ step-failed: 'blah-blah', timestamp: '' }

on a

function in the

class would be super helpful

ac•8/7/25, 3:46 PM

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 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!

berkant•8/10/25, 6:17 PM

d3v1an7•8/11/25, 3:51 AM

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 deploy

wrangler 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 error

Attempt 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.

Wow I ran command "npx wrangler workflows list" from cli. After that I can deploy workflows.

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.do

step.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

neverthrow

neverthrow

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

nvm my code had edge case that causes infinit loop, thank good I'm using cloudflare AI gateway and all those repeated requests were cached
