Proposed fix: [Azure OpenAI] 401 'Unauthorized. Access token is missing, invalid, audience is incorrect (https://cognitiveservices.azure.com), or have expired.' — API key sent as Bearer, wrong token s
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Use api-key header for keys (AzureOpenAI(api_key=...)), or azure_ad_token_provider with scope https://cognitiveservices.azure.com/.default (cloud-specific for sovereign clouds); refresh tokens via a provider rather than a static token.
Option: Match auth header/scope to credential type [evidence: documented_workaround]
Applies when: Azure OpenAI clients
Steps:
1. Keys: send api-key header (use AzureOpenAI client, not a generic OpenAI client with Bearer)
2. Entra: get_bearer_token_provider(cred, "https://cognitiveservices.azure.com/.default")
3. Sovereign clouds: use the cloud-specific cognitiveservices audience
Expected: Requests authenticate.
