the extension doesn't find any suggestions but "Quick fix" does

[HarmonicPool]

Hi I'm having a hard time getting the haskell-language-server features working in VSCode

I have worked previously in haskell in VSCode without problem, but the paused for a month or so

now when setting up a project I was getting errors like

The Haskell (<project>) server crashed 5 times in the last 3 minutes. The server will not be restarted.

thinking there was a problem with my project structure or something I tried doing things by hand running haskell-language-server-wrapper by hand, eventually getting some errors that helped me definitely more than the above error

once managed to run haskell-language-server-wrapper successfully, re-opening the project doesn't show the error but still, the hls features are not present

if it can help the line below is unable to find suggestions by pressing Ctrl+Space but on hover the "Quick fix" options recognises that the most probable module just needs an "s" more

Edit: reopening the project still raises the The Haskell (<project>) server crashed 5 times in the last 3 minutes. The server will not be restarted. error

@hasufell thanks for the help

following the steps you suggested ( https://github.com/haskell/vscode-haskell#investigating-and-reporting-problems )

I get the following output (repeated 3 times)

Perhaps the problem is in this line

ERROR hls:	Fatal error in server thread: SQLite3 returned ErrorBusy while attempting to perform step: database is locked

do you know which database is talking about here?

[hasufell]

haskell/haskell-language-server#2931

[HarmonicPool]

@hasufell removing ~/.cache/ghcide starts the LSP server at the second try and so it doesn't crashes, meaning no more error, but still there are no suggestions available

[HarmonicPool]

I found out that launching vscode from my usual shell works just fine, the problem is present only when launching from the nix-shell environment created using the files present in the input-output-hk/plutus-apps repository, so is likely not a problem of the extension
