Package com.tnsai.llm.errors

Class AnthropicProviderErrorMapper

java.lang.Object
com.tnsai.llm.errors.AnthropicProviderErrorMapper
All Implemented Interfaces:
ProviderErrorMapper
public class AnthropicProviderErrorMapper extends Object implements ProviderErrorMapper
ProviderErrorMapper for Anthropic's Messages API. Parses Anthropic's error envelope: 

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

Anthropic error types mapped to LLMException.ErrorType:

  • authentication_error → AUTHENTICATION_FAILED
  • permission_error → AUTHENTICATION_FAILED
  • not_found_error → MODEL_NOT_FOUND
  • rate_limit_error → MODEL_OVERLOADED (retryable)
  • overloaded_error → MODEL_OVERLOADED (retryable)
  • api_error → SERVER_ERROR (retryable)
  • invalid_request_error → INVALID_REQUEST (or CONTEXT_TOO_LONG when message contains "max tokens")
  • HTTP 5xx → SERVER_ERROR; 4xx → INVALID_REQUEST

Captured headers: retry-after, anthropic-ratelimit-*, request-id, anthropic-version.

Since:
0.5.0 (issue #87)

      public AnthropicProviderErrorMapper()

  • 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
