have anyone got "An RPC result was not disposed properly" when calling a workflow from a hono route?

Gabriel FranciscoOP•6/20/25, 3:15 PM

there is no disposables at this flow, but I keep getting this error

could it be that you do not await the create call to finish before exiting the hono route?

Gabriel FranciscoOP•6/20/25, 9:19 PM

good hypothesis, but its not that

Gabriel FranciscoOP•6/20/25, 9:19 PM

I use the instance id, right after too, ensuring the create is awaited

Gabriel FranciscoOP•6/20/25, 9:20 PM

it seems like a bug on hono or workflows

Elsa k🦮•6/20/25, 9:20 PM

Yes

rbravo•6/21/25, 1:55 AM

Hey, If I have a WF instance that has a sleepUntil, and I use .terminate it should cancel all the following executions that are inside this workflow, right? Right now even if I terminate the instance it keeps the execution.

It is recurring, at least locally, when creating a workflow. My code is very simple:

    .post('/:integration/fetch', zValidator('param', z.object({ integration: z.string().min(1) })), async (ctx) => {
        const { integration } = ctx.req.valid('param')
        const instance = await ctx.env.HistoryIngestion.create({
            id: integration,
            params: { integrationId: integration },
        })
        await ctx.env.Jobs.put(
            `workflow:${integration}`,
            JSON.stringify({ instance: instance.id, status: 'pending', progress: 0, startedAt: Date.now() }),
        )
        return ctx.json({ success: true }, 202)
    })

    .post('/:integration/fetch', zValidator('param', z.object({ integration: z.string().min(1) })), async (ctx) => {
        const { integration } = ctx.req.valid('param')
        const instance = await ctx.env.HistoryIngestion.create({
            id: integration,
            params: { integrationId: integration },
        })
        await ctx.env.Jobs.put(
            `workflow:${integration}`,
            JSON.stringify({ instance: instance.id, status: 'pending', progress: 0, startedAt: Date.now() }),
        )
        return ctx.json({ success: true }, 202)
    })

Hi, is there anyway to turn on verbose logging. I'm having some problem while building a crawler using workflows. While the links expand, it somehow leads to memory leak. Couldn't find the root cause for this.

GGabriel Francisco its not the case. why would you think that?

koraytaylan•6/28/25, 12:45 PM

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 FranciscoOP•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 FranciscoOP•6/28/25, 1:16 PM

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

Gabriel FranciscoOP•6/28/25, 1:16 PM

lots of silly limits

Gabriel FranciscoOP•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 FranciscoOP•6/28/25, 1:17 PM

very bad dx

Gabriel FranciscoOP•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 FranciscoOP•6/28/25, 1:27 PM

yep, I'm watching the containers 101 right now, that is my hypothesis too

Gabriel FranciscoOP•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

of the error is not set. Is that expected? Makes it hard to communicate data from the failed step to the recovery flow

MithushanJ•6/30/25, 2:10 PM

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

alex (he/him)•6/30/25, 6:07 PM

Any way we can get

step.waitForEvent

step.waitForEvent

not count towards the total step count per workflow, similar to

step.sleep

step.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

Gabriel FranciscoOP•6/30/25, 6:52 PM

how can I see the logs of a specific instance? I can't find it on observability

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.do

step.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.
