because the whole point workflows (at least for me) is to not have any time limits. code running inside a step not supposed to have any such limits i believe. then i guess i would try splitting that specific step into multiple smaller ones to see it will still have this issue assuming the step being too big could be the reason.

Gabriel Francisco•6/28/25, 1:15 PM

the problem is that the step is very small in code. but I receive tons of data via tcp

Gabriel Francisco•6/28/25, 1:16 PM

that was my assuption too, but my experience has been totally different

Gabriel Francisco•6/28/25, 1:16 PM

lots of silly limits

Gabriel Francisco•6/28/25, 1:17 PM

there is a very low memory limit (128mb), cpu time limit, http requests limit, even the quentity of active timers (setTimeouts)

Gabriel Francisco•6/28/25, 1:17 PM

very bad dx

Gabriel Francisco•6/28/25, 1:18 PM

and the cpu time limit I think its a bug on the node_compat of "node:net", no way I'm getting this limit from my code, it's probably internal

Gabriel Francisco•6/28/25, 1:28 PM

but I feel very bad for workflows, I thought it was a better fit for use cases like mine, but with limits similar to workers http it makes it unusable for data management

meow•6/29/25, 4:29 PM

Hey guys, I’m trying to return workflow instance ids after createBatch. But the instance.id always return null. It works fine locally but not on production. Anyone experience this?

ac•6/29/25, 9:56 PM

Every time we end a workflow "early", e.g. just return a value before all the steps are done, this is logged as an Error in CF observability/logs section (even though it is definitely not an error). Is this a known issue? Will it be addressed?

Wilco•6/30/25, 7:40 AM

Hi all, I'm trying to catch an error from a step (when the retry limit is reached) and it seems the causecause of the error is not set. Is that expected? Makes it hard to communicate data from the failed step to the recovery flow

What is the time limit for a step to finish in a workflow that has multiple steps

Any way we can get step.waitForEventstep.waitForEvent not count towards the total step count per workflow, similar to step.sleepstep.sleep

alex (he/him)•6/30/25, 6:08 PM

We have a hard time to strucutre our workflows to stay under the 1024 step limit. We either hit the cpu time limit of 5 minutes if we do multiple tasks in one step, or we hit the step limit if we do each task in a separate nested workflow

ddsgadget•7/1/25, 11:12 PM

This has been an issue forever. I have posted about it many times and others have experienced the same thing. I have never seen Cloudflare acknowledge it, though. Supposedly, if you JSON stringify the response, you won't see an error, but even Cloudflare doesn't do that in any of the examples. Bottom line, this is a bug in workflow, but it doesnb't seem like they will ever fix it.

Seekerdasbatatas•7/2/25, 9:01 AM

While the invocation might show the invocation as errored/canceled, it's not directly related if your workflow instance threw or not, it's a side-effect of how we guarantee durable execution internally. You should refer to the instance logs (in the Workflows tab, in dash),to see if an instance failed or not.

But this is something that we should definitely fix in our logging pipeline, so sorry about that :MeowHeartCloudflare: , we'll try to get it fixed :soontm:

ac•7/2/25, 12:18 PM

Thank you! That'd be hugely helpful for us, especially since it makes it show on our dashboard that we have hundreds of thousands of "Errors" (most of which are actually just workflows). Makes it very hard to understand our system health.

unsync•7/3/25, 4:19 PM

We started on workflows and this puzzles me, if I have a long running workflow, I get close to zero observability of what happen inside my steps until the whole execution is done ?

martinhoest•7/3/25, 7:43 PM

I must be fooling about with Workflows and Observability - or is it normal that a failing step of a Workflow will not add meaningful logs to Observability?

The error here is thrown within step.dostep.do but it is nowhere to be found from the logs tab of the worker. I also cannot find anything on the Instance ID of the workflow invocation.

ddsgadget•7/4/25, 2:17 AM

Thank you! yeah, I understand the error has no impact on the actual workflow. But, it is really annoying to see the errors in the dashboard when there is no real workflow error.

Gabriel Francisco•7/4/25, 3:46 PM

is it possible to see the logs of a particular step? this seems basic but I can't find a specific filter for that

Gabriel Francisco•7/4/25, 4:37 PM

my workflows are going to some weird "Waiting" state, even without sleeps, I would like to see what is happening but can't find any logs

martinhoest•7/5/25, 6:45 AM

What's the expected output in logs if one Workflow triggers another Workflow, but the instance ID of the latter already exists?

Will I need to loop through all created instances from await this.env.WF_FILING_INGEST.createBatch(batchParams);await this.env.WF_FILING_INGEST.createBatch(batchParams); and call their status()status() function?

Or it might be better to check for existing instance before creating new?

Clarifying Maximum Workflow instance creation rateMaximum Workflow instance creation rate Limit

The createBatch documentation says

call to createBatch is treated the same as a call to create (for a single instance) and allows you to work within the instance creation limit.

Does this imply that when using createBatchcreateBatch , if you were to create 100 instances per batch (the maximum), that you could create 10,000 instances (100 per batch * 100 calls) per 10 seconds?

I understand there are other limits that might kick in (e.g. Maximum number of queued instances), but this example is meant to clarify the creation rate limit.

trying to move one of our cache gen into workflow

list active users

store into r2

my initial thought is having a workflow just to fetch users, then it kicks off another workflow to fetch and cache data based on user id
or better to just have a single workflow?

Seeking advice here, i want to create scheduled workflows. I want to create periodic tasks (i.e. daily at 9am, 1st day monthly), and one-time tasks (date xx at yy time). These workflows are dynamically added by the user via an api request to the worker. I’m using Hono to handle routing.

What should i use to achieve this?
