From 43d7f40b0ebee1456b6a19b26628857be4f258c0 Mon Sep 17 00:00:00 2001 From: Aaron Lippold Date: Tue, 18 Nov 2025 14:32:10 -0500 Subject: [PATCH 1/6] fix(openai-adapters): extend auth header override to support x-api-key Extends the fix from PR #8684 to handle x-api-key header in addition to Authorization header. Background: - Continue sends duplicate auth headers where the first is malformed - PR #8684 fixed this for Authorization header - Same issue affects x-api-key header used by some OpenAI-compatible APIs Changes: - Rename function to letRequestOptionsOverrideAuthHeaders (more generic) - Check for both Authorization AND x-api-key in requestOptions.headers - Remove default headers if custom ones are provided - Handles Headers object, array, and plain object formats Impact: - Fixes authentication with APIs that use x-api-key header - Enables use of MITRE AIP and similar enterprise endpoints - Maintains backward compatibility with existing configs Related: #7047 (duplicate headers bug) Extends: #8684 (Authorization header fix) Tested-with: MITRE AIP endpoints using x-api-key authentication Authored by: Aaron Lippold --- packages/openai-adapters/src/util.ts | 57 ++++++++++++++++++---------- 1 file changed, 37 insertions(+), 20 deletions(-) diff --git a/packages/openai-adapters/src/util.ts b/packages/openai-adapters/src/util.ts index 3b33dfb799c..a0d352ea0e3 100644 --- a/packages/openai-adapters/src/util.ts +++ b/packages/openai-adapters/src/util.ts @@ -159,34 +159,51 @@ export function customFetch( return patchedFetch; } - function letRequestOptionsOverrideAuthorizationHeader(init: any): any { - if ( - !init || - !init.headers || - !requestOptions || - !requestOptions.headers || - (!requestOptions.headers["Authorization"] && - !requestOptions.headers["authorization"]) - ) { + function letRequestOptionsOverrideAuthHeaders(init: any): any { + if (!init || !init.headers || !requestOptions || !requestOptions.headers) { return init; } - if (init.headers instanceof Headers) { - init.headers.delete("Authorization"); - } else if (Array.isArray(init.headers)) { - init.headers = init.headers.filter( - (header: [string, string]) => - (header[0] ??

Changed regex from /^(?:gpt-5|gpt-5-codex|o)/i to /^(?:gpt-5|gpt-5-codex|o[0-9])/i to only match: - gpt-5, gpt-5-codex (GPT-5 series) - o1, o3, o4, etc. (OpenAI O-series reasoning models) This prevents false positives for model names like: - openai/gpt-oss-120b (Cloudflare Workers AI model) - ollama/... (Ollama models) - Any other model with provider prefix starting with "o" Tested with openai/gpt-oss-120b - now correctly uses /v1/chat/completions instead of /v1/responses.
