matlab-ls repeated launch and crush

[yutaka-shoji]

Describe the bug

It seems that an error occurs when the matlab-language-server connects with MATLAB. When checking the logs of matlab-ls from the output of VSCode, the following output was observed:

ReferenceError: location is not defined
~~~~~~~~

Versions:

• MATLAB R2023b
• VSCode: latest
• matlab-language-server: 1.2.0
• Windows10

[yutaka-shoji]

Hi @yutaka-shoji, can you try this again with the new release of the extension (v1.2.1) and let us know if you are still encountering this issue?

[yutaka-shoji]

@dklilley Thank you for response and your work! However, my vscode still does not seem to be able to connect to MATLAB. (Is anyone else experiencing this problem?)

[dklilley]

Thank you for trying this! Unfortunately, we have not been able to reproduce this ourselves, and have not received any other reports of this.

[yutaka-shoji]

@dklilley Thanks for the reply. I reinstalled vscode just to be sure, but it did not solve the problem. What is this error around?The js code in the source is obfuscated, so I have no idea what the error is from my end.

[YiZhiRikka]

Same problem with same vscode matlab-language-server log. The MATLAB started 5 times successfully seen from task manager but MATLAB language server crashed 5 times.
