Seeing the following error when a script returns a pydantic object. Currently on v1.554.0. This error wasn't happening on older versions, but unsure when exactly things changed/broke.

Minimal script to repro:

from pydantic import BaseModel

class Foo(BaseModel):
    bar: int

def main():
    return Foo(bar=1)

from pydantic import BaseModel

class Foo(BaseModel):
    bar: int

def main():
    return Foo(bar=1)

AttributeError: 'tuple' object has no attribute 'replace'

how to share a variable inside the flow like a global variable?

for example I want to have a variable which updated and also re-used in a flow. for example in a while loop or for loop

rubenf•10/6/25, 9:14 PM

@tl_jacob are you sure we every supported it? We could add support but you can make it work with model_dump()

rubenf•10/6/25, 9:14 PM

from pydantic import BaseModel
class Foo(BaseModel):
    bar: int

def main():
    return Foo(bar=1).model_dump()

from pydantic import BaseModel
class Foo(BaseModel):
    bar: int

def main():
    return Foo(bar=1).model_dump()

tl_jacobOP•10/6/25, 9:22 PM

@rubenf yes, I'm pretty sure it was supported at least on 1.500.1.

but you can make it work with model_dump()

yep, that's my current approach!

Not a blocker for us, but I did want to flag it

rubenf•10/6/25, 9:23 PM

I will try but more likely it's a pydantic change rather than on our side

rubenf•10/6/25, 9:23 PM

but will try

tl_jacobOP•10/6/25, 9:24 PM

Makes sense, thanks @rubenf !

rubenf•10/6/25, 9:24 PM

not yet but it's on our backlog

aeb-dev•10/6/25, 9:25 PM

is there any workaround?

rubenf•10/6/25, 9:25 PM

write a dummy script and use the result everywhere

aeb-dev•10/6/25, 9:26 PM

imagine multiple steps in a for loop, 1-2-3. 2 returns a value to be used by the next iteration when executing 2 again

rubenf•10/6/25, 9:27 PM

setFlowUserState

Rrubenf setFlowUserState

srobik836•10/7/25, 8:01 PM

I use windmill API to update variable/resource, and then load it. do you think is not correct way?

rubenf•10/8/25, 5:59 AM

It's very similar but flowuserstate is scoped to that flow and ephemeral to it

paales•10/8/25, 9:33 AM

Any known issues that might be causing a step in a flow to wait for 30±0.2 seconds about 70% of the time before it starts executing? I've added a log on the top of the bun execution and it takes 30 seconds for it to log so I don't think it is because of my code directly.

rubenf•10/8/25, 9:35 AM

@paales if you want help you will want to provide a ton more context. Does it happen for all bun jobs, or just that one, can you reproduce on other instances, other worker groups, etc

paales•10/8/25, 9:36 AM

@rubenf I was afraid you were going to say that, will get back to you once I've investigated further. Thanks for the prompt response.

fjørdlek•10/8/25, 7:06 PM

yes e.g:

https://app.windmill.dev/scripts/get/c2f993b8523d29b6?workspace=alex#foo=%22asdfadfs%22

https://app.windmill.dev/scripts/get/c2f993b8523d29b6?workspace=alex#foo=%22asdfadfs%22

will prefill the ui with foo = asdfadfs

zphr•10/8/25, 9:24 PM

Is there a way to make it so a script / flow doesn't log its args at all? Trying to point a webhook towards wmill but the webhook pushes 300kbs of data and I would be seeing this thousands of time a day

i would still want to see the job history / logs / return data, just trying to avoid the args

Daten•10/9/25, 1:38 PM

Every time I try copy field data from Windmill, it ends up copying the entire page/selected element, is there a way to stop that behavior?

Diego•10/9/25, 2:15 PM

in App editor ?

Diego•10/9/25, 2:15 PM

I should have fixed that

Diego•10/9/25, 2:15 PM

are you on latest, if not, which steps to reproduce

Daten•10/9/25, 2:18 PM

Yep, in app editor, I will check what version I am on and get back to you. I last updated about a week ago so its possible

Daten•10/9/25, 2:23 PM

CE v1.552.1-3-g0ba5e3e9c

(Soon to be enterprise, just waiting for Finance approval)

Diego•10/9/25, 2:30 PM

Yes it’s a very recent fix

Diego•10/9/25, 2:30 PM

Try upgrading

Daten•10/9/25, 2:36 PM

Will do, thank you!

trying to trigger a flow via email but can not connect with smtp because certificate validation fails. windmill is self-hosted on k8s. how do I pass my certificate to it?

sprinkle•10/9/25, 10:36 PM

When using git sync, is there a way to control the Git username format of each commit?

paales•10/10/25, 11:15 AM

Hey Guys, I'm having a little trouble with iterators and viewing progress in the UI. I usually process batches of 100 items and when starting a workflow. It currently agressively limits what information can be shown (showing 20 of 100 items, click to load more). And it doesn't show the first or last item that is currently being processed in the UI. In an ideal scenario I would like to see the last item that has been fully processed as the currently active item in the iterator in the UI.

rubenf•10/10/25, 11:21 AM

aeb-dev•10/10/25, 11:31 AM

I couldnt find a way, is there a specific place I can mount a certificate so that windmill pick it?

aeb-dev•10/10/25, 11:31 AM

even better with certmanager if possible

Rrubenf @paales update your instance

paales•10/10/25, 12:29 PM

Works like a charm

Thanks a lot! Amazing

Trey•10/10/25, 1:13 PM

hey everyone, is there any way to pass resource as param when using Rust? I can achieve this in Python.

in Python: (works)

class supabase(TypedDict):
    url: str
    key: str


def main(supabase_auth: supabase, workflow_id: int, message: str):

class supabase(TypedDict):
    url: str
    key: str


def main(supabase_auth: supabase, workflow_id: int, message: str):

in Rust: (does not work)

#[derive(Serialize, Debug)]
struct supabase {
  url: String,
  key: String
}

fn main(supabase_auth: supabase) -> anyhow::Result<Ret> {

#[derive(Serialize, Debug)]
struct supabase {
  url: String,
  key: String
}

fn main(supabase_auth: supabase) -> anyhow::Result<Ret> {

thanks
