Failed to authenticate 401

[codeasashu]

I am having trouble using this plugin. I am using tag v3.3.3 of this plugin in neovim. On using any chat feature (such as quick reply), I am getting the error: "Failed to authenticate 401". Copilot is enabled in my github account.

I tried adding some print to the curl_get function and this is the output:

I tried making this request separately in terminal:

curl -H "authorization: token ghu_<hidden>" https://api.github.com/copilot_internal/v2/token

{"message":"Bad credentials","documentation_url":"https://docs.github.com/rest","status":"401"}

However, it works when I use following header, this time with 404 error:

curl -H "authorization: ghu_<hidden>" https://api.github.com/copilot_internal/v2/token

{"message":"Not Found","documentation_url":"https://docs.github.com/rest","status":"404"}

I am having following 2 files in ~/.config/github-copilot dir:

1. hosts.json
2. versions.json

Content of hosts.json:

{
  "github.com": {
    "user": "codeasashu",
    "oauth_token": "ghu_<hidden>"
  }
}

Content of versions.json:

{"copilot.lua":"1.13.0"}

I doubt if https://api.github.com/copilot_internal/v2/token endpoint is even a valid REST endpoint?

It is valid endpoint otherwise the plugin would not work. Is copilot.vim (or copilot.lua) working for you?

[codeasashu]

@deathbeam yes, copilot is working fine. Also tested with vscode, and it is working fine there

[deathbeam]

After some looking around vscode is storing their token elsewhere. But closing this for now, the requests we are making are correct so I think the issue is with the token and that is not really possible to solve in the plugin I dont think, especially when its givng you bad credentials. Could be proxy issue, could be copilot.lua issue. Would at minimum recommend using copilot.vim at least and see if that helps
