LSP autocompletion in React components not working in rescript@13.0.0-alpha.4 / rescript@13.0.0-alpha.5 #1187
Description
I created a new project with create-resctipt-app (vite template). Then I updated rescript to 13.0.0-alpha.5 and changed the @rescript/react version to 0.16.0-beta.1.
I found out that the LSP has some problems Inside of react components. Lets explain it with some screenshots:
- Hovering over functions works
- But the autocompletion inside JSX doesn't work
- Even above the jsx code it fails
- After downgrading to
13.0.0-alpha.3(i have the same issues in alpha 4), autocompletions works again

Thanks for trying out. You're right, no problems in
rescript@13.0.0-alpha.4, after removing all node_modules and reinstalling again. But still no autocompletion inrescript@13.0.0-alpha.5. Could you try it as well?I'm using NVIM v0.12.4 and LSP v1.72.0
Fix empty completion (rescript-lang#1188)
