Do we have any updates on this? I'm building a complicated queue with durable workers now as a workaround but this would make it easier

hey, how cloudflare workers with multiple environments deal with workflows?

Gabriel Francisco•6/18/25, 8:00 PM

should I put one workflow at the root of the wrangler.toml or should I create a workflow for each env?

Gabriel Francisco•6/18/25, 8:00 PM

the first one seems more correct but it produces a warning

Aalex (he/him)True. But an sdk client or a zod validator isn’t serializiable anyway, right?

ddsgadget•6/19/25, 10:53 AM

You should have a separate workflow for each environment. Just change the name of the specific workflow in the wrangler.toml for each environment and leave everythng else the same in the workflow definition in the toml and it will work. Cloudflare will build a separate workflow for each environment using the same exact class. hpe that makese sense

Gabriel Francisco•6/23/25, 1:14 PM

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 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, 1:27 PM

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

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

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)OP•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)OP•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 Francisco•6/30/25, 6:52 PM

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

.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) })
