ok i see your point. to store the returned items you need to do,

const cats = await Promise.all(catList.map(cat => step.do(`get cat: ${cat}`, () => env.KV.get(cat))));

const cats = await Promise.all(catList.map(cat => step.do(`get cat: ${cat}`, () => env.KV.get(cat))));

this should work

I'm facing a lot of

A call to blockConcurrencyWhile() in a Durable Object waited for too long. The call was canceled and the Durable Object was reset.

while seeing spikes on my file upload endpoint, and this is happening on something internal on my Workflows, and those errors seems to be not retriable, how fix this?

I have some logic that returns from a Workflow

run

run

function after 2 steps if it doesn't need to progress further -- not an error, just a situation where it doesn't need to continue. I'm not throwing an error, just returning an object with some data, but for some reason it seems like this is still showing in the workflow's worker logs as an "Error" (but it shows up correctly in the Workflow logs as "Completed" -- no error). Is there something specific I need to be returning from the

run

Can I use a Tail Worker to handle logs from workflow steps?

The logs should be in the main worker that the workflow is attached to

ddsgadget•5/28/25, 7:29 AM

@alex (he/him) I have looked everywhere and can never find logs for any steps in a workflow. Maybe they are somewhere but I cant find them. This is single biggest weakness of workflows right now - logs are incredibly difficult to find for steps and this makes debugging them close to impossible. they should put the logs for each step on the actual step in the dashboard. This is what most other workflow platforms do - the logs for any workflow step are immediately visible in a UI for a step. i guess the only thing to do is send the logs to an outside service from each step, which make things complicated.

This may be a bit off topic but I have a question for CF techs - why don't you guys buy/partner with the n8n project and integrate it over your services? Technologically it looks like a marriage made in heaven! It's almost like they built it for cloudlfare!

Hey, I'm implementing some workflow

await step.do("process-events", async () => {
  const eventsGroupedBySomething = [[], [], [], [], [], []]; // potentially ~10 groups with 100s of events each

  for (const events of eventsGroupedBySomething) {
    for (let i = 0; i < events.length; i++) {
      const event = events[i]!;
      const { embedding, summary } = await generateEventSummary(event);
      await db
        .insert(schema.eventVector)
        .values({ id: nanoid(), eventId: event.id, embedding, summary });
    }
  }
});

await step.do("process-events", async () => {
  const eventsGroupedBySomething = [[], [], [], [], [], []]; // potentially ~10 groups with 100s of events each

  for (const events of eventsGroupedBySomething) {
    for (let i = 0; i < events.length; i++) {
      const event = events[i]!;
      const { embedding, summary } = await generateEventSummary(event);
      await db
        .insert(schema.eventVector)
        .values({ id: nanoid(), eventId: event.id, embedding, summary });
    }
  }
});

await step.do("process-events", async () => {
  const eventsGroupedBySomething = [[], [], [], [], [], []]; // potentially ~10 groups with 100s of events each

  for (const events of eventsGroupedBySomething) {
    for (let i = 0; i < events.length; i++) {
      const event = events[i]!;
      const { embedding, summary } = await generateEventSummary(event);
      await db
        .insert(schema.eventVector)
        .values({ id: nanoid(), eventId: event.id, embedding, summary });
    }
  }
});

await step.do("process-events", async () => {
  const eventsGroupedBySomething = [[], [], [], [], [], []]; // potentially ~10 groups with 100s of events each

  for (const events of eventsGroupedBySomething) {
    for (let i = 0; i < events.length; i++) {
      const event = events[i]!;
      const { embedding, summary } = await generateEventSummary(event);
      await db
        .insert(schema.eventVector)
        .values({ id: nanoid(), eventId: event.id, embedding, summary });
    }
  }
});

and I'd want to wrap the inner loop in a

step.do

step.do

for retries but then I could really quickly hit 1024 steps limit. Maybe I could invoke separate workflow in the inner loop to just handle processing the event? But then my

generateEventSummary

generateEventSummary

might throw 429 error. I guess sending queue message for every event and handling it in separate worker might be a better approach? What would be the "idiomatic" CF approach? Thanks!

Maybe I missed a step, but do I need to manually setup a Service binding for my workflow? I have a worker which accepts fetch requests, and the same worker defines 3 different workflows. Locally everything seems to run fine via the toml file. When I deploy I can see the workflow deploys happening, however when I goto

<MY_WORKER>/production/settings#bindings

<MY_WORKER>/production/settings#bindings

<MY_WORKER>/production/settings#bindings

<MY_WORKER>/production/settings#bindings then workflows are not shown. I was going to add them manually as a service, but am I going to have to do this for every deployment?

you could use kv to store state and track which

events

events

events

events and

i

i have been inserted already, so that way on retry you would just check the kv for where to start. - depending on db you might also want to do all the inserts as a batch after

events.length

events.length

events.length

events.length has been processed, which would reduce the number of kv writes to track
