Hello @JohnJyong, do you have any comments? The only issue left to be fixed is disabling embedding models with a dimensionality > 2048. I'd like to ideally throw an error like this but I'm not sure how other vdb's like relyt are handling it

@roadgoat19 Hello , sorry for the late response, we have working on some new features regarding RAG recently. Please resolve the conflicts and we can proceed with this PR. :)

@crazywoola I've fixed a lingering merge conflict, could you rerun the workflows please?

Hello the API Tests (3.10) failed and there are some lint errors in the superlinter.
You could run ./dev/reformat to resolve linting issues. @roadgoat19

@crazywoola Hello I believe I've fixed this issue causing the api tests to fail. However, I am a little unsure about how to fix the linter errors in the .env.example. When I run dev/reformat, it says that basically every single key is out of order. This issue persists even with the .env.example taken straight from the current main branch of dify. Is there a command I can run to fix this issue /or how should I proceed?

[crazywoola]

Hello there are some conflicts here. And still got a lint error. I think you need to upgrade ruff and sync deps by ./dev/sync-poetry.

Thanks @crazywoola, and sorry for the delay here. I'm picking this PR up for @roadgoat19, and have resolved all conflicts and updated the dependencies. Let me know if anything else needs adjusting!

[crazywoola]

Hello @ejscribne Thanks for picking this up, please resolve those conflicts again :)

[ejscribner]

Hey @crazywoola just fixed the conflicts, let me know if anything else needs to be done. Thanks!

Hey @crazywoola sorry for the delay fixing this, added a healthcheck to be sure the resource is ready for the tests. It should fix the issue.
