I'm pretty sure I've found and fixed the issue.
I've published a new version to the JetBrains Marketplace, until that gets approved you can download the new version here: https://github.com/rockofox/intellij-haskell-lsp/releases/tag/1.2.1

Please reopen if it still doesn't work properly.

I am using 1.2.1 and get the same issue right now. Can you re-open and investigate @rockofox? I am happy to support if needed.

[rockofox]

@jamesrweb Do you have haskell-language-server installed on your machine? Are there any errors?

[jamesrweb]

I investigated and it seems to be a problem with the ghcup version of the LSP. When running that, the plugin throws this error.

When using the brew version, the plugin works fine.

I am assuming this is NOT the plugins issue with that being the case and IS a problem of the ghcup version somehow.

You can close this again, but thank you for your reply and patience and the awesome work 🙏🏻❤️

@jamesrweb Hey-hey, could you describe what is the issue with ghcup version of the LSP?

[jamesrweb]

I have no idea 🤷🏻‍♂️. I just know that when I install it with brew it works and when I used ghcup it didn't.

@sumanthegde @develmac Please try the new release. It should work with ghcup-installed language server as well.
It's probably not available on marketplace yet, so I've put up a release here.

Tried 1.3.1, got this notification: "Haskell Language Server not found. Make sure it is installed properly (and is available in PATH or via ghcup), and restart the IDE." However ~/.ghcup/bin is in PATH, and contains HLS:

@sumanthegde
I've redone a bunch of logic and properly tested it with a clean GHCup installation this time, and it should work now.

I've pushed a new version (1.3.2) to marketplace (awaiting review) and to a GitHub release

[sumanthegde]

It's able to connect to HLS now. Thank you!

[rockofox]

Great to hear!
I'll close this issue now, as the problem seems to be solved.
Feel free to reach out again if any problems, old or new, arise ^^

@rockofox not sure why my previous comment is gone, but anyway I also tested it and now it works great! Just amazing, I have been waiting for something like this for years, thank you so much!
