It works fine when I run haskell-language-server --debug directly in the directory.

Include debug information

Execute in the root of your project the command haskell-language-server --debug . and paste the logs here:

what happens if you delete all the caches (ghcide, hie-bios, etc)?
mpickering had a similar symptom and it fixed for him (iirc was an error related with hiedb sqlite in that case)

isovector · 2021-08-03T18:01:15Z

Removing neither of ~/.cache/ghcide nor ~/.cache/hie-bios helped.

pepeiborra · 2021-08-03T21:53:09Z

What version of VS Code are you using? Could you try upgrading it?

pepeiborra · 2021-08-03T21:54:17Z

The new lsp version adds support for semantic tokens, and I think old versions of VS Code do not stick to the LSP specification in the declaration of semantic tokens support, which probably breaks the parser in the lsp-types package

isovector · 2021-08-04T00:26:04Z

I'm running 1.58.0, which is less than 2 months old (latest is 1.58.2.) Think this could be the problem?

berberman · 2021-08-04T01:07:27Z

I reported this in #2068. VS Code 1.58.2 still doesn't work for me.

pepeiborra · 2021-08-04T07:48:23Z

I think we can close this as a duplicate of #2068
