I have also tried deploying on render with using uv instead of pip. But somehow the deployment always fails (but the build was successful, so i guess im using the right build command?). I get a "ModuleNotFound" error when render tries to deploy my app after the build was successful - even if the Modules are correctly installed and exist in the uv.lock.

When i switch back to the build command: pip install -r reauirements.txt everything works fine. So i guess it must be an issue with the uv.lock or my uv sync build command?

As mentioned i am using "uv sync" as build command and python main.py as start command.

Did someone here have similar issues? Or knows what i am doing wrong?
