"Failed to parse WorkspaceConfiguration params" with pyright LSP server

[subsonik]

Summary

When trying to open any .py file with Helix 22.03 and the pyright LSP server configured, Helix crashes out as soon as the file is opened with the following backtrace:

thread 'main' panicked at 'Failed to parse WorkspaceConfiguration params: Error { code: InvalidParams, message: "Invalid params: invalid value: string "", expected relative URL without a base.", data: None }', helix-lsp/src/lib.rs:216:22

v0.6.0 worked fine, presumably this is because of PR #1684.

Reproduction Steps

I tried this:

1. hx -vvv models.py

I expected this to happen:

• The editor is opened, I can edit the file, and pyright LSP server works as expected with diagnostics, completion, etc.

Instead, this happened:

• The editor immediately crashes out with a backtrace.

Seems to rely on pyright rootPath which was deprecated for rootUri. But that in turn was deprecated by workspaceFolders. Pyright checks workspaceFolders frist, then rootPath (but not Uri).

I guess we should specify all three, the LSP spec is getting ridiculous.

[archseer]

Can you test 84e799f ?

Thanks for the quick reply! :)

[archseer]

Opened an upstream issue, I'm out of ideas

[archseer]

Can you try 8adf0c1 ?

[subsonik]

It works, thank you so much!

If I specify the 'config' option in languages.toml, even if its just an empty string, everything works as expected. But, if I comment 'config' out, LSP functionality no longer works, and after 10 secs or so, I get the error:

Async job failed: request timed out

I can live with specifying an empty 'config' option to get it to work, but should I raise this as a separate issue?

[archseer]

Can you provide logs for both success and failure cases? I need more information to diagnose this.

[subsonik]

Of course.

Here it works fine, with config = "":
