Plugin LSP4IJ (0.7.0): Error while starting language server 'qute' (pid=null)

Using the latest IntelliJ on latest Windows version, I'm getting the following error when starting the IDE:

Error while consuming LSP 'textDocument/inlayHint' request

Have you this problem when IJ is scanning files or indexing something?

Is Qute support is available after this error?

Have you this problem when IJ is scanning files or indexing something?

Yes, I think it's during scanning. At least it's when the project is loaded in IntelliJ.

Is Qute support is available after this error?

Syntax Highlighting works partly.

[angelozerr]

Yes, I think it's during scanning. At least it's when the project is loaded in IntelliJ.

Great! I'm working on this issue with #570 (not a trivial issue)

@mr-mos could you please install:

• https://github.com/redhat-developer/intellij-quarkus?tab=readme-ov-file#testing-nightly-builds
• https://github.com/redhat-developer/lsp4ij?tab=readme-ov-file#testing-the-ci-builds

and tell me if it is working better. The main idea is to start language servers only when all indexing step is finished for all projects. In this case Qute, Quarkus language servers starts and visit Java classes which are ready to collect data. The IJ startup should be a lot improved.

Any feedback are welcome!
