Ah, just noticed @myconull asked the same question two days ago: workflows.

He's also using Remix as just Worker (not Pages). Could someone on the cloudflare team have a look at his repo, pls?

You can’t deploy a Workflow as part of a Pages app (which is likely what the default Remix build is trying to do).

Deploy the Workflow separately (as a Worker) and bind to it from your Pages app / call it over HTTP.

I've been digging into workflows a lot, but recently I've been getting this error:

The destination execution context for this RPC was canceled while the call was still running.

Hi Matt, the repo that I posted is using the latest Cloudflare Remix template using Workers instead of pages. And the issue was still occuring.

Walshy•11/5/24, 7:22 PM

The Remix template is currently building as a Pages project then deploying as a Worker which is likely why this is happening. Remix has native support for Assets now so we're moving that over, you can track that here: https://github.com/cloudflare/workers-sdk/pull/7170

Ah thanks for the reply. Can I ask - what determines Pages vs Worker? I was previously looking for "pages_build_output_dir " in .wrangler

No automatic unique id is generate when create method is called without id. Is it a usual behaviour or a bug in local?

mau•11/6/24, 9:05 PM

I’m exploring Cloudflare Workflows to streamline email notifications for parents on our e-learning platform. Our goal is to notify parents based on specific events they’ve subscribed to, like when a student completes a quiz, finishes a topic, or needs a daily/weekly family summary. We want to set these notifications to trigger at defined times, tailored to each user’s preferences. If anyone has insights or tips on setting up these kinds of recurring notifications effectively, I’d love to hear them!

Thanks in advance for your help!

Dmitry•11/7/24, 5:02 AM

Was doing some load tests and noticed that if I start a bunch of workflows quickly the dashboard kinda becomes really slow

Dmitry•11/7/24, 5:02 AM

Anyone else experience this?

Dmitry•11/7/24, 5:02 AM

I was only starting like 26/s tho

Dmitry•11/7/24, 5:03 AM

Once I stop the load test and wait a few min for the workflows to finish .. it loads fine

oof2win2•11/8/24, 12:06 AM

hey there. i'm working with a HTMLRewriter and i seem to be getting errors with an RPC stub not being disposed. i think it's the rewriter because of essentially the same error here. is this an issue on my side or an issue within workers?

Dmitry•11/8/24, 1:54 AM

I also noticed... I have a sleep step like so

await step.sleep('wait on something', '1 second')

await step.sleep('wait on something', '1 second')

but here it says the wall time for this step is

254ms

254ms

.. any idea why it's lower than what the wall time should be?

Dmitry•11/8/24, 1:56 AM

it would also be nice if it showed the sleep step name (i.e - "wait on something").. even tho it is just a sleep.. instead of just showing the name as "Sleep"

Dmitry•11/8/24, 1:57 AM

Maybe like

wait on something (Sleep)

wait on something (Sleep)

Dmitry•11/8/24, 1:58 AM

It's easy to tell what sleep step it is, since I only have 1 sleep step.. but if I had multiple.. it would be easier to tell which sleep step is what very quickly

arbfay•11/8/24, 12:40 PM

I hit a wall with Workflows:

Serialized RPC arguments or return values are limited to 1MiB

Serialized RPC arguments or return values are limited to 1MiB

which I think happens when the returned values of a step are larger than 1MiB.

What is the workaround for worklows? For service bindings, it is to use streams.

arbfay•11/8/24, 1:12 PM

Yeah merged 3 steps into 1. Not ideal.

Seekerdasbatatas•11/8/24, 3:04 PM

I understand, my future OSS side project that I've wanting to do might solve that: is to allow some nice abstractions on top of workflows (like natively supporting other storage providers, and other cool stuff that i've been noting down)

felixv•11/8/24, 10:09 PM

Hey

,

loving workflows so far, one thing I noticed is when you use the

Trigger

Trigger

Button to trigger a workflow, the

Params

Params

are submitted with some extra characters

While when I trigger it via cli, it works without any problems.

npx wrangler workflows trigger create-campaign-from-url-workflow --params='{"url":"https://www.backlinkgpt.com"}'

1984 Ford Laser•11/9/24, 7:09 AM

But tbh not sure if the

Trigger

Trigger

button doing the stringify, or if wrangler not stringifying would count as a bug here

felixv•11/9/24, 7:51 AM

Thanks

for the feedback. I think for the button you can only enter „valid json“ so a stringified version is not validated in the modal text input. But yeah you are right if i input a non stringified json, after clicking trigger it gets stringified which makes my workflow fail.

But the stringified cli trigger payload works

Lucas G•11/9/24, 10:21 PM

I noticed this as well. You can use a JSON parse when testing through the dashboard but keep in mind that this doesn’t happen when you are actually sending JSON to the workflow when you create a run so don’t leave it in for production
