Not quite - something we're iterating on, specifically because returning a single (size limited) string can be confusing here.
Dhmm okay, from my testing the type of the API docs are wrong. It does indeed return an object value
SBut confusingly, the output property of the Binding InstanceStatus contains the step results, not the workflow output.
You mean in local dev, right? what's the behaviour on a real workflow?
Dhmm it seems like you are right! I just tested it again with my deployed workflow and I do indeed get the workflow output there.
Ssorry about that 
it should be an unknown there - i'll look into it but I think it's an openapi 3.0 limitation

AAny updates or issues I can subscribe/follow to, to track progress on this?
Aseems like there might be some sort of outage? when i create new workflows, they have no steps, and when I try to pause or terminate the instances in the dashboard, those API calls return 500 errors like:
Athey also all have a start time of "pending"
Aoh wait - i think i'm running up against the 100 concurrency limit 
Ai would have assumed that workflows that aren't actually running (and are just sleeping) would not count towards the 100 concurrency limit...?
Ahow long is "eventually"? I'm seeing many instances, whose first step is a simple
await step.sleep('wait 24 hours', '24 hours'), which have been stuck in the "running" phase for many hours (30+)Athis is apparently deadlocking my whole account, since these instances which should be
Waiting are actually Running, and counting towards the 100 concurrency limit
Sif you can send me your account id, workflow name and instance id I can look it up 
Supdate your
@cloudflare/worker-types and should be on WorkflowEvent.instanceId SFYI y'all, we've bumped step limits again to 1024 
Athanks for your help! if you look at this one, the instance has been stuck in the "running" status for >24 hours
Awhen it should actually be Waiting state
Athis is a serious issue for us because it's causing us to hit the 100 concurrency limit
Awe're actually rebuilding our own task system outside of workflows because it's so broken 
SYou can try to terminate those hanging ones, to free up space - feel free to send any instance thats stuck to my dms (to not clog up this chat)
Ci love y'all

WHowdy all, I'm trying about workflow and saw this doc to running it locally, https://developers.cloudflare.com/workflows/build/local-development/, is there a way for me to test out the workflow? I know that
npx wrangler workflow targets production api. Do I need to setup a local worker to call my local workflow?Cloudflare Docs
Workflows support local development using Wrangler, the command-line interface for Workers. Wrangler runs an emulated version of Workflows compared to the one that Cloudflare runs globally.

FIs there a way to delete workflows on our accounts? I can’t seem to find it either in the dashboard or api
FOops! What happens if you delete the worker bound to a workflow? Can that workflow still be used by another worker?
HI'm using workflows and I really like the built-in design to retry individual steps, very much like a multi-queue solution for each step.
However, I'm also using queues to trigger N instances of the workflow as I want to space out some external calls, so I'm using delay with the queue.
But I'd very much like the workflow to receive the original batch.
This would allow for a much more robust acknowledgement and retry mechanism. If the workflow has access to the JS API of the queue batch, it will be able to control acknowledgment of the message. By retrying the queue message, it will be able to revert back executed steps by retrying the queue message and triggering a new workfow instance resetting the state.
The step sleep is not enough for that.
Currently, I need to resort to acknowledging all messages in the queue batch as soon as the workflow is triggered regarless if it's successful.

ADoesn't seem to work with
wrangler types --experimental-include-runtime
DAssuming that I have a workflow which at the end returns something, can I later retrieve that value using
env.WORKFLOW.get(id).status().output (something like a sort of kv?) or is it something one shouldn't rely on (e.g. expires after some time)?DAh, I guess this is part of the following limit:
Retention limit for completed Workflow state: 3 days; 30 days
AJust as an FYI, I think there's some out of date info in the docs referring to
event.params (e.g. https://developers.cloudflare.com/workflows/get-started/guide/) whereas I now think it's event.payload (changing this fixed it for me so guessing event.params was old?)
WAsking a question re the
the limits:
I am using this to get the size of the return value
however, I notice that the value returned and the actual value shown when an error is thrown can be quite different.
how can I reliably check what is the size of a return value before returning it?
(guess this is not specific to Workflows, but it's relevant in this context because a workaround I've seen is to use ReadableStream, but that wouldn't work because of the max persisted state per step limit)
Serialized RPC arguments or return values are limited to 1MiBthe limits:
- maximum persisted state per step is 1MiB
- Workers return value can only be 1MiB

MAlways the code as it was deployed. We’re thinking about how to enable some options here. Lots of divisive opinions.
BHey guys is it not possible to remove a deployed workflow?
EHi everyone, any luck setting up Bugsnag?
Ois it possible to increase the number of maximum outbound requests, higher than 1k? splitting the workflow into multiple executions probably is a possibility but it seems kinda weird as a limit
Yagreed ^
Yhi will the
like the cloudflare dashboard shows the steps status so its easier to track on which step is currently processing.
i return
step_name be added anywhere in future in status ?like the cloudflare dashboard shows the steps status so its easier to track on which step is currently processing.
i return
step_name along with the data as a workaround
ᴀHey team, is there an ETA on when the concurrent execution limit of 100 will be bumped? would the workflows in await steps count toward the concurrent execution limit?
we have workflows which have a total execution time of less than 10 m and want to be able to run 50K per minute and it is not a constant rate.

MNot yet. Are you asking for ~833/sec or much higher? Have you tried using a Queue to manage a backlog / back off?
ᴀyes 900/s or more concurrent WF, right now we are using the queue and are event based, liked the workflow model which fits our use case, we want to have multiple campaign workflows which would create multiple subscribers workflow. subscribe workflow will perform bunch steps and send out the content
MWe’re still early-ish in the beta so won’t be 900-1000+ concurrent overnight. Recommend using a Queue here - even at scale, a Queue is going to give you the mechanisms to manage the backlog
Cany update on the infinite queued instances dilemma. currently, i'm unable to start a new instance of any workflow account wide.
MThis should have been fixed last week. Can you share your account ID so we can see what’s off here?

MThis should be fixed now: we believe we fixed the root cause on this (metadata out of sync).
