When does this happen?

IF LiteLLM Proxy returns 'missing Editor-Version header for IDE auth' when forwarding requests to GitHub Copilot API, even if the header is provided in the client's extra_headers.

How others solved it

THEN Configure the required Editor-Version and Copilot-Integration-Id headers in the LiteLLM model configuration using the extra_headers parameter in litellm_params. This ensures the proxy forwards them correctly. For token authentication, pass the GitHub token via extra_body in the SDK call.

model_list:
  - model_name: gpt-4
    litellm_params:
      model: github_copilot/gpt-4
      extra_headers: {"Editor-Version": "vscode/1.85.1", "Copilot-Integration-Id": "vscode-chat"}
