Error Ducklake: Writing parquet file fails.

ExecutionErr: execution error: "HTTP Error: Unable to connect to URL http://localhost:36867/api/w/testsr2/s3_proxy/_default_/datalake/main/states2/ducklake-01997aa2-1513-75ee-a66e-ff5a6e3d9aa3.parquet?uploads=: Forbidden (HTTP code 403)" Metadata within Postgres (Neon) looks good, S3 Browser up- and download looks good. Using a stand alone DuckDB / Ducklake with same S3 and Postgres infrastructure works just fine, so I think, something is wrong with my Windmill configuration. ...

Error: Connecting to database: pool timed out while waiting for an open connection

Windmill server and worker containers deployed to ECS exit with the above error. The RDS postgres logs show could not receive data from client: Connection reset by peer, suggesting a connection is being made but the client (server/worker containers) are killing the connection. RDS instance is db.t4g.large. Confirmed the max connections setting is still the default (which allows ~900 connections for this instance size). ECS tasks are deployed on Fargate with 2 vCPU and 4GB Memory. I don't see any evidence of memory or CPU constraints in monitoring. ...

Docker

I'm having difficulty figuring out how do handle a very simple scenario. I have a flow where a step generates a file, and pushed it to S3. I have a subsequent step where I need to run a docker image that would run a script to download that file and execute docker code on it. Since I cannot mount any files, how can I download a file and have it available to the code inside the docker container. What is the general process for executing a docker image that needs to have access to a file?...

Parsing resource content $res

Hi there, I am using windmill v1.513.1 and I define an Input which has type array and item type "Items are resources". Now, the ressources are passed to the next step as something like "$res:/path/to/resource". This $res is breaking everything. Is it intended to appear and how do I parse the resource in a subsequent script using the go-library's GetResource(string) ? Thanks for hints

Using perpetual script to trigger flow

I want to create a system that will listen to an event from an external service and trigger a flow to process the data. My initial through is to use a perpetual script as the listening service and trigger the flow when an event was captured from the listening service. However, I can't seem to find a way to trigger a flow using code. what is the best way to setup a listening service that can utilize flow? Is there a way to natively trigger flow using something like inner flow mechanism but for script?...

Using custom components in an app

Anyone have any experience with making custom components? I am wondering what is common practice when making exchanging info between the component and a script? Currently i am setting the output of the component to my "question" then a background script sees a change in the output and runs with that new output from the component. In the script that branches out to all those actions thats needed. Is there some easier way? I will give an example so its easier to undestand. Lets say i want a component to look up adresses. By default the component is in its search state, then by writing into a searchfield it will set an output and a background script will run with those perameters, eg {"action": "search_query", "query": "abc"}. the script will then do some things and will return something like {"action": "search_suggestion", "suggestions": [x, y, z]}, this will then trigger a recalculation of the component and it will see those perameters and rerender itself. This will go on in a "loop", back and forth where everything is stateless. I am wondering if there is an easier approach? Do people use APIs? In that case how, and can you use background scripts in an app for that?...

MCP version update?

The current implementation of MCP at Windmill works on SSE. However, newer MCP clients have forced Streamable HTTP, preventing connections. Information: https://modelcontextprotocol.io/specification/2025-06-18/basic/transports#streamable-http...

Can't select scripts to add to flow

I have written a bunch of new graphql scripts and when I try to create a new flow and add the script it does not show up in the library or when I search. I have been using windmill for a while now and this is the first time that my files are not showing up file making flows so I think it might be a bug

Script Cache

In testing caching for script results, I noticed my script that is tagged to run on a Windows Agent executes the script each time it is run. The same script without a tag (I.e. using regular workers) does return the cached result immediately. Is this expected behavior? My goal was to cache output from a script run against our active directory to populate a dashboard. It doesn't need to be executed with every app refresh because the data changes infrequently....

I was an admin of our Windmill account and now I don't even see it. Was our account deleted?

We just paid for 3 users on Sep 6th and I was one of the Admins, yet now it looks like our account doesn't exist or I've been kicked out of it.

Agent Tags

Based on the docs one should be able to restrict workers to specific workspaces using custom tags like “tag(workspace1)” as an example. I deployed a windows agent with a tag “ad-dev(infra)” but users in other workspaces are able to use that tag in their scripts. Please advise if this is not the correct path for me in trying to restrict which workspaces are allowed to use the windows agents I have configured.

Input doesn't get preprocessor output in the flow

I have a flow that is triggered by the email trigger. I've added a Preprocessor step that maps the trigger event to the other data structure. Let's say, preprocessor returns this object: { account: "Account Name", amount: "5" } When I test the preprocessor, it works as expected. ...

Question about Licensing and AWS subscription

My company's group excited to get to use Windmill. We have been building some thing on the CE and are considering the move to EE. The problem is getting finance to OK a 3rd party expense is cumbersome and painful. We have the green light to spend on AWS though. So, I was thinking we could pay for the AWS Marketplace version, but we want to use ECS (and are currently doing so) and not EKS. Would the AWS Marketplace version be workable if we are only deploying on ECS and not EKS? Additionally, what does 10 seats, 4 compute units mean? For regular billing there are different seat types and different computer units. ...

website outside windmill using a button

I want a button in my Windmill app that opens a website directly (in a new browser tab). e.g https://google.com Right now: If I use Windmill’s “Go to a URL” action, it treats my link as if it’s an internal Windmill app route. That causes errors like “App not found” instead of opening Google externally....

Worker configuration

Hello ! If I want to reduce the number of workers, I realized I need to modify the compose.yml file. How can I ensure I don't have to restart the container after updating the number of workers?...
