No GitHub token found.

[mvds314]

I am using this plugin under Windows 11 (Neovim 0.10.1) and the copilot.vim plugin.

I keep gettting the following error:

No GitHub token found, please use :Copilot auth to set it up from copilot.lua or :Copilot setup for copilot.vim

Copilot itself works.
On my Linux machine, the plugin does work with this config.

I use the following config for the plug:

{
    "CopilotC-Nvim/CopilotChat.nvim",
    branch = "canary",
    dependencies = {
      -- { "zbirenbaum/copilot.lua" }, -- or github/copilot.vim
      { "github/copilot.vim" },
      { "nvim-lua/plenary.nvim" }, -- for curl, log wrapper
    },
    -- build = "make tiktoken", -- Only on MacOS or Linux
    -- build = vim.fn.has("win32") == 1 and "powershell -ExecutionPolicy Bypass -File Build-LuaTiktoken.ps1" or "make"
    -- opts = {
    -- debug = true, -- Enable debugging
    -- See Configuration section for rest
    -- },
    config = function()
      require("CopilotChat").setup {
        debug = true, -- Enable debugging
        -- See Configuration section for rest
      }
    end,
    lazy = false,
    -- See Commands section for default commands if you want to lazy load on them
},

My complete config can be found here .

I tried a couple of things:

• enable/disable the tiktoken
• Reinstall the plugin
• Reinstall copilot.vim

Anyone any ideas on how I can make this plugin work?

Does ~/.config/github-copilot/hosts.json exist?

[mvds314]

Yes, on my windows machine it's located under: c:\Users\MyUsername\AppData\Local\github-copilot\hosts.json

It has the following content:

{"github.com":{"user":"<my_github_username>","oauth_token":""}}

Only my linux machine it looks the same, only the token is different.

https://github.com/CopilotC-Nvim/CopilotChat.nvim/blob/d43fab67c328946fbf8e24fdcadfdb5410517e1f/lua/CopilotChat/copilot.lua#L78C16-L114

Could it be how the paths are separated? Your setup looks about right to me.

[mvds314]

I don't know, my programming knowledge within the neovim infrastructure is limited.
What I do know is that, under windows, ~ does not redirect to the home folder. Maybe it does if you use it in lua when writing neovim plugins.

To test it, can I call this function in Neovim like this?

:lua require("CopilotChat.copilot").find_config_path()

[mvds314]

Okay, slowly getting there... I just manually changed the line 83 config = vim.fn.expand('~/AppData/Local')
Copilot thinks it should be this ;-)
config = vim.fn.expand('$LOCALAPPDATA')

Now I'm getting another error:

Failed to get response: {
exit = 35,
message = 'get https://api.github.com/copilot_internal/v2/token - curl error exit_code=35 stderr={ "curl: (35) schannel: next InitializeSecurityContext failed: CRYPT_E_NO_REVOCATION_CHECK (0x80092012) - The revocation function was unable to check revocation for the certificate." }',
stderr = '{ "curl: (35) schannel: next InitializeSecurityContext failed: CRYPT_E_NO_REVOCATION_CHECK (0x80092012) - The revocation function was unable to check revocation for the certificate." }'
}

Solution to the curl problem can be found here.
Just set: allow_insecure = true

This means replacing line 83, as described in the previous post, indeed solves this bug.

Alright, created PR for the fix (with fallback to original value when not found)
