Awesome! Could you also help me out with the JSX type errors? I'm not using React Danke.

lgrammel commented 5 months ago

The JSX issue is risky to fix. Can you try installing just the React types and see if that helps?

  "@types/react": "^18.2.8",

Fixes it for me (only getting the Mistral error now)! Can I ask you to keep this issue, because it's very non-obvious for Node users?

Encountering same issue on express backend without react types. Resolved by installing types as a devDependency. Maybe add this to the document for express users?
