Hi chaps, relatively new to workflows. We have a relatively weird use-case in mind. Each user of our software will have "work/jobs" enqueued that will need to be processed. The caveat is that each bit of work must run sequentially. I was thinking that this could be accomplished by having a long/infinitely-long running workflow for each user that sleeps for x seconds, wakes and checks for work - processes it if it exists - otherwise goes back to sleep (repeat forever). Would something like that be achievable with workflows? With CF, we only pay for compute time so I wouldn't have thought the costs of this would be too onerous vs. using something like Lambda

Durable Objects with alarms that call a worker every x seconds? Is your sequential requirement per-user or for the entire work/jobs queue?

SakuraFC•4/30/25, 8:22 AM

I am seeing interesting issues with workflows. When I try to return simple object {} (empty object) as a state, workflow always logs exception but does work. Took me half a day to try and figure out what was going wrong despite it working. So far the only workaround I found is to return stringified object and from the step and then convert it back to the object and use in the remainder of the workflow. Not sure if it's a bug or expected.

Sequential requirement is per-user, not for the entire queue. Actually we'd ideally have multiple guaranteed sequential workflows per user

boop•4/30/25, 8:55 AM

In that case you could just use workflows and a queue if you expect to go over the instance creation limit.

The workflow could consume the jobs you've added in the queue, and the steps inside the workflow would be your sequential processing per job

Is anyone experiencing any issues with workflows getting stuck, l have some workflows that have around 165 instances stuck in running state, showing 0 steps in the UI, and l can't pause or terminate them

I might have identified a bug related to waitForEvent.

Here's the relevant code:

export class SimpleWorkflow extends WorkflowEntrypoint<
  Env,
  SimpleWorkflowPayload
> {
  async run(event: WorkflowEvent<SimpleWorkflowPayload>, step: WorkflowStep) {
    console.log("Simple workflow started", event.payload);

    await step.do("testing timeout", async () => {
      console.log(`Initializing test: ${event.payload.name}`);
      const eventResponse = await step.waitForEvent("waiting for event", {
        type: "test",
        timeout: 10000,
      });
      console.log("Test event received", eventResponse);
      return { status: "initialized" };
    });

    console.log("workflow complete");
  }
}

export class SimpleWorkflow extends WorkflowEntrypoint<
  Env,
  SimpleWorkflowPayload
> {
  async run(event: WorkflowEvent<SimpleWorkflowPayload>, step: WorkflowStep) {
    console.log("Simple workflow started", event.payload);

    await step.do("testing timeout", async () => {
      console.log(`Initializing test: ${event.payload.name}`);
      const eventResponse = await step.waitForEvent("waiting for event", {
        type: "test",
        timeout: 10000,
      });
      console.log("Test event received", eventResponse);
      return { status: "initialized" };
    });

    console.log("workflow complete");
  }
}

export class SimpleWorkflow extends WorkflowEntrypoint<
  Env,
  SimpleWorkflowPayload
> {
  async run(event: WorkflowEvent<SimpleWorkflowPayload>, step: WorkflowStep) {
    console.log("Simple workflow started", event.payload);

    await step.do("testing timeout", async () => {
      console.log(`Initializing test: ${event.payload.name}`);
      const eventResponse = await step.waitForEvent("waiting for event", {
        type: "test",
        timeout: 10000,
      });
      console.log("Test event received", eventResponse);
      return { status: "initialized" };
    });

    console.log("workflow complete");
  }
}

export class SimpleWorkflow extends WorkflowEntrypoint<
  Env,
  SimpleWorkflowPayload
> {
  async run(event: WorkflowEvent<SimpleWorkflowPayload>, step: WorkflowStep) {
    console.log("Simple workflow started", event.payload);

    await step.do("testing timeout", async () => {
      console.log(`Initializing test: ${event.payload.name}`);
      const eventResponse = await step.waitForEvent("waiting for event", {
        type: "test",
        timeout: 10000,
      });
      console.log("Test event received", eventResponse);
      return { status: "initialized" };
    });

    console.log("workflow complete");
  }
}

Whenever

waitForEvent

waitForEvent

waitForEvent

waitForEvent fails due to a timeout exception, the step is retried as expected.

However, once the step re-runs, I’m no longer able to send events—the workflow appears to be running, but the event cannot be received or triggered anymore.

is that due to worker updates during execution? its not very clear what this means.

queued

queued state and will never run.

I have 4K+ messages going into dead-letter-queues because workflows can't be instantiated.

@James / @Diogo Ferreira any help would be appreciated, as this product was working perfectly up until yesterday moring.

And a question here:
is it better to split up heavy workflows into iterating through steps, or rather break it down that each pagination runs in a sub-workflow?

Entirely depends on what you're doing? A single Workflow is (IMO) easier to reason about, keeps the code in the same place, and if the task is tightly bound, simplifies error boundaries and tracking

Start with one and (later) only add more if you need to fire off sub-Workflows.

Yes, we have the same issue and this seems to be a bug. All our workflows work perfectly fine, but throw exceptions in the dashboard after they finish. We generally return, {success:true} at the end of a workflow, which should be fine according the docs, but somehow this is an error? It's not clear what the actual format is for a return, especially the last step in a workflow. The only way around this for us has been to just terminate workflows at the end, otherwise they will all throw exceptions even if they work perfectly fine.

I've got some intances of a workflow queued that don't seem to be getting picked up. Have been in this state for a while. Is there any way to tell in the dashboard why these aren't getting picked up?

I found that the only reason that it throws (in the beginning for us) without impacting our workflows, is when we return an object or array from the step.

You are most likely facing the same issues as am having in this thread: workflowsI am not sure what has happened with.

@Diogo Ferreira / @Thomas Ankcorn we seem to have a few more of the race condition issues

Hey there! I'm new to using Workflows and I've got a question.

I'm creating a workflow that depends on a mTLS certs binding for making requests. For some reason, mTLS certs bindings don't work locally (env.CERT is always empty) so I need to do

--remote

--remote

for it work.

The problem with that is that

--remote

--remote

also makes my workflow to run remotely as well. Ideally, I'd like to run workflows locally while still being able to have certs work.

Is there a way to make this work?

Thanks in advance!

I'll ask the team, but if the mTLS bindings aren't supported locally, then... there's not a way to make it work locally.

Update: yes, not supported locally, sorry. Working on better support across modes — some things like mTLS cert and/or Workers AI are hard to emulate locally.

I don't mind if I need to run mTLS remotely. My goal is to use mTLS remotely while simultaneously running the workflow locally

Is that possible?

Matt Silverlock•5/2/25, 4:40 PM

No, you can’t do this - that’s what I mean when you can’t make this work locally. We’re working on support for “mixed mode” to help solve but not yet ready.

How can we use cloudflare queue or workflow to process my users campaign where each campaign can send 50k to 100k messages

i want to schedule to a later date that i can do myself

i want to know if queue will be best or workflow will be best for this scenario

because i think if i send 100k messages then each msg in a queue will be a batch of 500 msg, then other users have to wait until 1 user campaign is over even if we have concurrency for 4-5

whereas in workflow we can invoke as many instances upto 4500 and queue other ones and each workflow can have multiple steps ( so i think it can run in parallel for 4500 campaigns)

what will be best? i am really confused, please help

Pretty sure Workflows is built off of Queues. So read docs of both and weigh up pros and cons of your use case - e.g. auto retries etc

@andy Yeah I asked this same question a few days ago. As far as I can tell, you can't see the consol
