Do not use latest commit https://github.com/microsoft/vscode-js-debug . use v1.74.1.

Manually

git clone https://github.com/microsoft/vscode-js-debug
cd vscode-js-debug
git pull
git fetch --all --tags
git checkout tags/v1.74.1
npm install --legacy-peer-deps
npm run compile

With Packer

use {
  "microsoft/vscode-js-debug",
  opt = true,
  run = "npm install --legacy-peer-deps && npm run compile",
  tag = 'v1.74.1'
}

Thanks for this! And @JbIPS for the packer config.

I think it would be better to set the tag to v1.* though, to still get the latest updates. This should probably be in the readme...

[tomaskallup]

Using v1.* also causes this error for me, had to lock it to v1.74.1.

Seems like they released the breaking change as v1.75.

[jessevanassen]

It should be fixed now and working with the main branch of vscode-js-debug again.

I got everything work, tested on latest commit https://github.com/microsoft/vscode-js-debug/commit/df2210162933263ec92b73eba560e33bec3eca9d.

should we close this issue ?

I am still experiencing this on 1.75.1, 1.74.1 works fine though. Really strange, anyone else?
