when i run workflow locally, occasionally i get this error ``` workerd/jsg/setup.c++:39: fatal: V8 f

is there a reason why?

Is it possible to set concurrency limits on a workflow?
Kind of like how Trigger.dev does it (https://trigger.dev/docs/queue-concurrency).

My use case is to use browser rendering in a workflow and not allow more than 1 run at a time for this workflow in order to not go above the limitations of the browser rendering product.

I really like workflows, but just want to say that they are extremely difficult to debug, because the console.logs are not available anywhere. So all you see is the result of a step and have no insight into potential issues when something in the step goes wrong.

ddsgadget•5/12/25, 11:27 PM

You are not alone. I've posted this issue on many ocassions. Workflow can run fine, but will show errors in the runs in the dashboard. Someone the other day commented that you must JSON stringify the response from each step and then JSON Parse it back in next step, if you want to get rid of these errors. I haven't tried it yet, and none of Cloudflare examples do this, but apparently that solves these errors.

Are there any limitations for local development on workflows that might affect the accuracy of

env.WORKFLOW.get(id)

env.WORKFLOW.get(id)

env.WORKFLOW.get(id)

env.WORKFLOW.get(id)?

After I invoke a long-running workflow in one codepath, a different codepath it sometimes cannot find that instance (i.e. I get

Error: instance.not_found

Error: instance.not_found

Error: instance.not_found

Error: instance.not_found). I've been unable to find a pattern for repro, except that it seems the codepath that invokes the workflow can successfully call

get(id)

get(id)

later, even in a different instance of the worker; whereas some other codepath will always get

instance.not_found

instance.not_found

instance.not_found

instance.not_found. I'm using the same binding for the same worker with the same workflow id.

J

johtso•5/14/25, 7:34 AM

I see one of the workflows examples shows waiting for a web hook event. How would you deal with the scenario of a web hook being received before the workflow begins waiting for it? Are events queued up in any way?

Jonathan•5/14/25, 1:15 PM

Are there any best practices for implementing a workflow that is used for starting and stopping third party services?

I was considering storing a lock in a durable object that states if the start workflow has already been executed you can only run the stop workflow but you still need to track the workflow instance id.

hmm, is this because being able to adjust retention for a workflow is "coming soon" so it's currently fixed at 7 days?

cg•5/15/25, 4:42 PM

Hi all!
I'm intersted in setting something up with Workflows, but I noticed on this page:
https://developers.cloudflare.com/workflows/build/trigger-workflows/

That:

Known issue: Restarting a Workflow via the restart() method is not currently supported and will throw an exception (error).

Known issue: Restarting a Workflow via the restart() method is not currently supported and will throw an exception (error).

Known issue: Restarting a Workflow via the restart() method is not currently supported and will throw an exception (error).

Known issue: Restarting a Workflow via the restart() method is not currently supported and will throw an exception (error).

Is this still true? It seems the page was last updated Feb 18 2025, but Workflows has been GA for a month or so now. Can anyone confirm if restart() still throws errors?

excellent. I'm sure it's already in the roadmap, but +1 to getting this implemented. It's probably the only thing keeping us from moving our pretty high volume workload over

ac•5/16/25, 1:36 AM

In the code that is calling env.WORKFLOW.create(), is there any way to wait for that workflow to complete to continue executing that code? (assume it's from another worker). I know I can call instance.status at some point after it's complete, but not sure how I know when that is, and I need some context from the workflow's result in this other spot before continuing.

I figure that I should probably restructure all of this at some point so that isn't necessary, was just trying to see if I could avoid restructuring too much of my code

T

tadhglewis•5/16/25, 4:10 AM

There's probably ways (looping until status changes) but it isn't recommended. Workflows are entirely async and there's no guarantee how quickly they'll be completed.

Instead your Workflow should emit a webhook back to where you process "workflow complete" once it's completed.

hey there, i've previously created workflows on DB changes with CDC and i created them based on some form of unique ID within the DB that I always knew was going to be unique. previously, when i backfilled CDC (say due to an outage etc), the old workflows just didn't get created but the new ones did - which is what i wanted. now when i do that though the worker errors as it can't create the workflow. is this an intended breaking change or no?

i think you could implement an abstract base class (which your actual workflow inherits) and then you could encapsulate the logic to capture error in this base class and add a message into a queue. then another worker would trigger and start that other workflow.

K

koraytaylan•5/20/25, 8:02 AM

it is interesting. i didn't know about such limitation. how about:
your current workflow would just be a proxy that adds those 600ids into a queue as 600 messages. then you could configure a worker that would trigger for those messages and create a separate workflow that only work for an individual image instead of trying to process all 600 in one workflow.

Jjohtso I don't think that works for the case of retry limits being reached

K

koraytaylan•5/20/25, 8:10 AM

i have what i described in a simpler way to log detailed error messages on what went wrong. so, from the highest level if i am able catch an error and process it, then i guess it should be possible to trigger another workflow. now that i also realize you might not even need that queue because you could consider this part as a separate step to just trigger that other workflow.

when i run workflow locally, occasionally i get this error ``` workerd/jsg/setup.c++:39: fatal: V8 f
