Command CocCommand clangd.install fails with error 'Failed to install clangd language server'

[jrmd54]

This error occurs on a fresh install.
I added coc.nvim plugin and built it with command 'npm ci'
coc-clangd is then downloaded automatically when vim is started.
Since there is no clangd binary yet in my ~/.config/ folder, i have to run the command ':CocCommand clangd.install' (as requested when i open a .cpp file).

But the command fails with the following error message:
[coc.nvim] Failed to install clangd language server: TypeError: Expected signal to be an instanceof AbortSignal
You may want to install it manually.. See https://clangd.llvm.org/installation.html.

Thank you very much for your insight.

From what i found it is possible this bug is caused by node-fetch (node-fetch/node-fetch#784).
I tried rebuilding coc-clangd from the repository with npm install, while changing version of node-fetch in package-lock.json, but it had no effect.
But maybe i did something wrong, i admit i am not very proficient with node.

What's your Node.js version?

[jrmd54]

It was 18.8.
Just in case i upgraded it to 20.11 (latest) and reinstalled coc-clangd plugin, but the error still shows up.

Tested with Node.js v18.19.0 but can't reproduce.

I made a fix in coc-clangd v0.30.2, give it a test please.
