integration test should be updated accordingly (to test the changes).
could you work on this, please (and fix linting too).

[heiko-hotz]

What is linting? And I don't want to publish my endpoint IDs to the repo - but then how will it know which endpoints to use?

I'm afraid I'm not familiar with integration testing tools (it was already a struggle to get pytest to run), so I'm not sure what needs to be done here :)

[heiko-hotz]

can someone offer guidance on what needs to be done here?

[moizsajid]

@marshmellow77 firstly set up poetry with linting and testing like explained over here https://python.langchain.com/docs/contributing/code#local-development-dependencies

Then run from make lint and make format from the respective module directory i.e. libs/vertexai or libs/genai (in your case it would be libs/vertexai) after activating poetry shell. Please let me know if you need further help!

For running integration tests, the command would be make integration_tests
