flow concurrency clarification

Hello ! I need clarification about concurrency. I have a flow with multiple scripts. This flow is scheduled every 30 minutes. I don't want a second flow to trigger if there's an execution in progress. The flow can sometimes last longer than 30 minutes... How do I configure it to wait for the flow to complete before launching the second one if the first one exceeds 30 minutes?...

AI agent development with Windmill

Good morning everyone. I have a silly question. Currently I am using Langchain to build an AI agent. I used n8n before and it's so easy but hidden all magical so I don't like it. But Langchain/langgraph with full backend code is very time consuming. I think Windmill can fit my case, but I don't see any tutorial or resource about it. Can someone drop a link or any suggestions? Thanks in advance....

Python DLT library in windmill? Compatibel?

Hi guys, used windmill for some simpel automations and love the platform. I have a project where I want to utilise the dlt-hub library. Is this compatible with windmill.dev? Since I see that you'll need a defined folder structure for dlt, something that seems against the paradigms of windmill?...

Constant high memory consumption

We have self hosted windmill on azure aks. We are using it to run daily python scripts. After a while windmill workers' memory caps at 2gb and stay there. The memory limit of the instance is also 2gb. Ignore the container creating line in the image.

Could not write file to azure blob storage

Hi, I started having the following error: Exception: Could not write file to S3 when I am trying to write a file to blob storage from a flow. It was working before and suddenly started failing. I am using the wmill.write_s3_file(s3_file_output, file_content) as per the docs. There is no change in the permissions from my side in Windmill or from dev ops side in Azure storage. Is there any change regarding writing files in the recent weeks? Any suggestions why this happens?

Questions regarding licensing

Hi, we are planning to use Windmill in our company. We want to use the self hosted version, as we are not allowed to use cloud-based services. Our plan was to use the free version for the first steps and after we see, that everything runs well, we want to upgrade to the enterprise version. A 30 day trial would not be enough. I just saw at the very bottom of the first table at the pricing page on the homepage, that there is an "X" at the row "commercial license". Does that means, that we cannot follow our plan, as we need an enterprise license from the very beginning? ...

Widget stopped working as runnable input

Hey everyone, I’m working on a public app in Windmill and ran into an issue with the List widget. Inside my list, I placed other input widgets (text fields, toggles, etc.). The inputs render fine, but when I try to use their values as runnable inputs, they always come through as null. Has anyone dealt with this before? it was already working until the 18th August, then it just stopped working....

Automated Tests in Windmill

What are the current best practices for end to end testing of flows? When I check https://www.windmill.dev/docs/flows/test_flows it only explains the manual approach. AI points to these docs as well. I would like to have a programmatic way so that flows can be tested in CI/CD pipelines. Mocking support would be important as well. Is there any way of doing that?...

Scripts, variables, resources disappeared from web interface

Hi, I can no longer see any of my resources, run history, variables or scripts within my self-hosted windmill web interface. I have multiple scheduled triggers and i can confirm that the automations are still working as expected and if i go to my (external) postgres database I can still see all the scripts/resources in there along with new logs coming in. So the issue is limited to not being able to see anything in the web interface. What i've tried so far: 1. Made sure i was in the correct workspace 2. Tried logging in as superuser and other users who have access to the scripts....

How to build a media pipeline around a S3 bucket and Docker

Hi, we're evaluating windmill.dev as an option to build a trigger based media pipeline. We have a bunch of locally maintaned docker containers doing different task (such as taking FBX files and doing format conversions for vendors) or transcribing media contents. I would like to achieve the following: 1. trigger a process with an input (which is a remote URL) 2. download the remote URLs contents into a folder...

Why does wmill flow generate-locks force rename my inline script filenames to generic ones?

Turn off just-in-time user creation

From the external auth with JWT docs:

This will make the app act such that the user authentified is the one that corresponds to the jwt payload. Windmill uses just-in-time provisioning by default and the user doesn't need to have been pre-provisioned for it to works.

I'd like to embed a windmill app and use jwt authentication, however I want to turn off JIT user provisioning. Is there a way to turn off this default behavior and require that the user already exists in windmill?...

Unable to trigger webhook via Google Push Pub/Sub

I have set a webhook trigger for my flow (and a script as well during debugging) and I am able to trigger it just fine via curl. I am also able to receive google pub/sub push notifications when I place a webhook via a testing service called webhook.site. However the moment I place my windmill webhook url (token in query) I do not receive the notifs on windmill. Not even a trigger.
