Class AzureOpenAIProviderErrorMapper

java.lang.Object
com.tnsai.llm.errors.AzureOpenAIProviderErrorMapper
All Implemented Interfaces:
ProviderErrorMapper
public class AzureOpenAIProviderErrorMapper extends Object implements ProviderErrorMapper
ProviderErrorMapper for Azure OpenAI Service — ninth pilot mapper.

Azure OpenAI uses the same error envelope as OpenAI itself: 


 { "error": { "message": "...", "type": "...", "code": "...", "param": "..." } }

The differences are operational, not envelope- level: Azure-specific error conditions (DeploymentNotFound, InvalidApiVersionParameter) appear under the standard code field; the response carries Azure correlation headers (x-ms-request-id, apim-request-id) for tying requests to Azure portal log traces.

Status mappings:

  • DeploymentNotFound (404) → MODEL_NOT_FOUND (Azure-specific: the deployed model name doesn't exist in this Azure resource)
  • InvalidApiVersionParameter (400) → INVALID_REQUEST
  • OpenAI-shared codes inherit the same routing as OpenAIProviderErrorMapper — rate_limit_exceeded → MODEL_OVERLOADED, context_length_exceeded → CONTEXT_TOO_LONG, invalid_api_key / Unauthorized → AUTHENTICATION_FAILED, etc.
  • HTTP fallback for unrecognised codes

Captured headers: retry-after, x-ms-request-id, apim-request-id, azureml-model-deployment.

0.5.3 (issue #87 follow-up — ninth pilot mapper)

      public AzureOpenAIProviderErrorMapper()

  • Method Details

    • providerId

      public String providerId()
      Specified by:
      providerId in interface ProviderErrorMapper
      Returns:
      short, lowercase provider id (e.g. "openai", "anthropic"). Used to route a raw response to the right mapper.

    • map

      public com.tnsai.exceptions.LLMException map(int httpStatus, Map<String,String> responseHeaders, String responseBody, String model, Throwable cause)
      Description copied from interface: ProviderErrorMapper
      Translate a raw HTTP error response into a typed LLMException.
      Specified by:
      map in interface ProviderErrorMapper
      Parameters:
      httpStatus - HTTP status code from the response
      responseHeaders - selected response headers (lower-cased keys); empty map if none captured
      responseBody - raw response body; mapper parses provider-specific envelope (e.g. JSON error.code)
      model - model identifier from the request, for the resulting LLMException.getModel()
      cause - underlying transport throwable, may be null when the failure is purely a non-2xx response
      Returns:
      typed LLMException with ProviderDetails attached

    • mapErrorType

      public Optional<com.tnsai.exceptions.LLMException.ErrorType> mapErrorType(String providerCode)
      Description copied from interface: ProviderErrorMapper
      Map a provider-native error code to a framework LLMException.ErrorType. Implementations should err on the side of LLMException.ErrorType.UNKNOWN for codes they don't recognize so that a new provider error doesn't fail the whole mapping path.
      Specified by:
      mapErrorType in interface ProviderErrorMapper
      Parameters:
      providerCode - native code (e.g. "context_length_exceeded")
      Returns:
      matching LLMException.ErrorType, or Optional.empty() if the mapper has no opinion
