Make Github copilot works with self-certificate in IntelliJ (Windows)

Problem

You can't login to Github to use Github Colpilot in your IntelliJ due to you are using self-certificate.
And you got this error message

Sign in failed. Reason: Request signInInitiate failed with message: self signed certificate in certificate chain, request id: 3, error code: -32603

Solution

Assume that you added your self CA cert into your OS "Trusted Root Certification Authorities".

1. Export the self-signed certificate in your OS.
   1. Start > search "Manage user certificates" > "Trusted Root Certification Authorities" > "Certificates" > Right click on your self-signed certificate > "All Tasks" > "Export..."
   2. Next > Choose "DER encoded binary X.509 (.CER)" > Next > Choose a path to save the certificate > Next > Finish
2. Convert the certificate to .pem format.
   1. Open a terminal > openssl x509 -inform der -in <exported_cert>.cer -out mycert.pem
3. Export the NODE_EXTRA_CA_CERTS environment variable.
   1. Start > search "Edit environment variables for your account" > "New..." > Variable name: NODE_EXTRA_CA_CERTS, Variable value: <path_to_mycert.pem>
4. Re-start your Intellij and this should now work
