Codex + Tencent LKEAP 401: It Was Not the Key

说明与用途

401错误是由于Codex期望Responses API，而腾讯LKEAP使用Chat Completions导致的协议不匹配。创建了本地Node.js代理来转换请求，并相应更新了配置。

问题

Codex misinterpreted a Tencent LKEAP endpoint as a Responses API, appending "/responses" to a Chat Completions URL and causing a 401 error.

结果

The 401 error was caused by a protocol mismatch; a local proxy successfully bridged the gap, allowing Codex to communicate with Tencent LKEAP.

工作流

• Inspect the final request URL for unexpected path patterns.
• Confirm the client’s wire protocol (Responses vs Chat Completions).
• Verify the upstream endpoint’s expected URL shape.
• If mismatch, either adjust the client config or implement a local protocol adapter.
• Set up a local Node.js proxy that forwards Responses requests to the correct Chat Completions URL.
• Configure Codex to point to the proxy and provide a dummy OPENAI_API_KEY.
• Test the setup with a real Tencent LKEAP API key and validate responses.
• Document any remaining gaps (streaming, tool‑call traffic, error mapping).
