Proposed fix: [Azure Identity] CredentialUnavailableError 'DefaultAzureCredential failed to retrieve a token from the included credentials.' — every credential in the chain unavailable (env vars set a
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Enable azure-identity logging to see each credential's failure; fix the intended one: set AZURE_CLIENT_ID/AZURE_TENANT_ID/AZURE_CLIENT_SECRET (or certificate vars) before startup, or run az login and verify with 'az account get-access-token', or configure managed identity. If a 401/403 comes back instead, a different credential in the chain authenticated — exclude unwanted ones with exclude_xxx_credential.
Option: Log which credential failed and configure the intended one [evidence: official_recommended_action]
Applies when: All DefaultAzureCredential failures
Steps:
1. Enable logging for azure.identity at DEBUG
2. For service principal: export AZURE_CLIENT_ID, AZURE_TENANT_ID, AZURE_CLIENT_SECRET before starting the app
3. For CLI: az login; az account get-access-token --resource https://management.core.windows.net (do not share output)
4. Optionally exclude credentials you don't intend to use
Expected: Token acquired by the intended credential
