Use "basic auth" instead of "Bearer token" with ollama ?

[vroussel]

Hi,
I have a remote ollama instance that expects Basic auth.

Based on https://codecompanion.olimorris.dev/configuration/adapters.html#example-using-ollama-remotely, here's the config I tried:

return {
    "olimorris/codecompanion.nvim",
    dependencies = {
        "nvim-lua/plenary.nvim",
        "nvim-treesitter/nvim-treesitter",
    },
    opts = {
        opts = {
            -- Set debug logging
            log_level = "DEBUG",
        },
        strategies = {
            chat = {
                adapter = "ollama",
            },
            inline = {
                adapter = "ollama",
            },
        },
        adapters = {
            opts = {
                show_defaults = false,
            },
            ollama = function()
                return require("codecompanion.adapters").extend("ollama", {
                    env = {
                        url = "<url>",
                    },
                    headers = {
                        ["Content-Type"] = "application/json",
                        ["Authorization"] = "Basic <XXX>",
                    },
                    parameters = {
                        sync = true,
                    },
                })
            end,
        },
    },
}

Here's what I see in the logs:

[ERROR] 2025-02-21 12:05:09
Could not parse the response from <url>/v1/models

Looking at the get_models code in ollama.lua, it seems that the headers here are declared locally and don't use what's in conf.
https://github.com/olimorris/codecompanion.nvim/blob/67a747eeab28456971979c8ee03c648135e8687c/lua/codecompanion/adapters/ollama.lua#L33C3-L38C6

  local headers = {
    ["content-type"] = "application/json",
  }
  if _cached_adapter.env_replaced.api_key then
    headers["Authorization"] = "Bearer " .. _cached_adapter.env_replaced.api_key
  end

Is there something I'm missing?
Thank you

Do you have a link to any source documentation?

Sorry I'm not sure what you mean by that ? Ollama is placed behind a reverse proxy that uses basic HTTP authentication.

I did some more testing and it turns out that codecompanion is working nicely if I specify a default model in my adapter's conf (I guess it doesn't try to get the models list in that case ?).
However, I can't switch to a different model (after selecting an adapter with "ga"), it gives me the same error as before. So everything seems to be working except that request to /v1/models.

Apologies I skimmed this yesterday and didn't properly understand the issue.

Could you try out #985 and let me know if it works?

Your config should now be:

return {
    "olimorris/codecompanion.nvim",
    dependencies = {
        "nvim-lua/plenary.nvim",
        "nvim-treesitter/nvim-treesitter",
    },
    opts = {
        opts = {
            -- Set debug logging
            log_level = "DEBUG",
        },
        strategies = {
            chat = {
                adapter = "ollama",
            },
            inline = {
                adapter = "ollama",
            },
        },
        adapters = {
            opts = {
                show_defaults = false,
            },
            ollama = function()
                return require("codecompanion.adapters").extend("ollama", {
                    env = {
                        authorization = "Basic", -- <---- Added this
                        url = "<url>",
                    },
                    headers = {
                        ["Content-Type"] = "application/json",
                        ["Authorization"] = "Basic <XXX>",
                    },
                    parameters = {
                        sync = true,
                    },
                })
            end,
        },
    },
}

So just added in the authorization = "Basic" line.
