How to use with self-signed certificates?

[aramirezreyes]

Hi! Thanks for the great tool.

Summary

I am facing an error when using copilot.el . The error has to do with using self-signed certificates, which prevent the communication with copilot.

• A good explanation of how this happens is given here: https://stackoverflow.com/a/71973332
• A similar error in the vscode extension is solved by installing this extension. https://github.com/linhmtran168/mac-ca-vscode/tree/main
• That one is based on this extension to allow node.js to honor those certificates: https://github.com/jfromaniello/mac-ca

The error message

This appears in the *copilot-language-server-log whenever the extension tries to communicate with the github servers, it it basically does not work.

What I have tried.

1. I tried installing the mac-ca certificates from here https://github.com/jfromaniello/mac-ca into the node version used by copilot.el
2. Then I modified ~/.config/emacs/.cache/copilot/lib/node_modules/@github/copilot-language-server/dist/language-server.js By adding this to the shebang #!/usr/bin/env node --require mac-ca/register

But unfortunately no luck. Do you have any pointers for this?

~probably insecure but you can try setting env NODE_TLS_REJECT_UNAUTHORIZED=0~ nvm
