Aura Language Server - Request textDocument/hover failed.

[scromiecaremore]

Summary

While in a separate project folder, I try to work with JavaScript code and get complaints from the Aura Language Server in the Output window. The error is:

[Error - 1:00:10 PM] Request textDocument/hover failed. Message: Request textDocument/hover failed with message: Cannot read property 'aura' of undefined Code: -32603

This is repeated whenever I hover on any text.

Steps To Reproduce:

1. Open VS Code.
2. Open a non-sfdc project folder
3. Open a javascript file
4. Hover on any word (for instance, I hover on "return", "catch", "finally", "try".

Expected result

The error

[Error - 1:00:10 PM] Request textDocument/hover failed. Message: Request textDocument/hover failed with message: Cannot read property 'aura' of undefined Code: -32603

Should not pop up on the Output window.

Actual result

The error

[Error - 1:00:10 PM] Request textDocument/hover failed. Message: Request textDocument/hover failed with message: Cannot read property 'aura' of undefined Code: -32603

pops up on the Output window.

I am getting this output error popping up all the time even when I just have a regular apex classes open in my VS Code.

I started getting this with the latest update that I ran... not sure if I was before but it's started force opening the output panel and even when I click on an LWC JS File.

Has anyone found the resolution to this problem, the LWC Language Server in the output panel keeps opening and at this point it's becoming annoying to close it every time or resize it to a small size to hide it, which then you have to restore again to work with SFDX grrrhhh :(

It is extremely annoying to have the Apex Language Server panel grab focus

Hello, I am facing the same issue. I have cloned the salesforce e-bikes app and the HTML keeps failing when hovered over the CSS classes. Extremely annoying as the output window is pulled into focus.

@scromiecaremore I'm not able to reproduce the issue you described. Are you still able to reproduce this?

If you are still able to reproduce this, could you describe the repro steps again, and add any missing details? For example, for step 2 ("Open a non-sfdc project folder"), in my project's directory I created /non-proj and then created /non-proj/test.js, and then used this for my JS file:

function test() {
  return 'this is a test';
}

When I hovered over return, I didn't get any errors.
