ResponseError: Unhandled method window/workDoneProgress/create

[K.Himeno]

Hello.

When connecting monaco-languageclient to typescript-language-server, an error occurs in the LSP and it shuts down.

I am looking for a way to avoid this problem.

Using:

• node -v: v18.19.0
• typescript-language-server@4.2.0
• monaco-languageclient@7.3.0
  • vscode-languageclient@9.0.1
  • vscode-languageserver-protocol@3.17.5

LSP startup commands

typescript-language-server --studio

The following sample was rewritten for typescript-language-server and verified.

• https://github.com/TypeFox/monaco-languageclient/tree/main/packages/examples/src/python

This server could handle it better by not crashing but as related issues show, the issue is really in the client announcing the support for window.workDoneProgress while not really supporting it. Why is that not being fixed?

EDIT: Following up in TypeFox/monaco-languageclient#586

Thanks for the quick Bug Fix!

Looking forward to the release.
