Class GroqProviderErrorMapper

java.lang.Object
com.tnsai.llm.errors.GroqProviderErrorMapper
All Implemented Interfaces:
ProviderErrorMapper
public class GroqProviderErrorMapper extends Object implements ProviderErrorMapper
ProviderErrorMapper for Groq — seventh pilot mapper.

Groq's chat-completions API is intentionally OpenAI-compatible at both the request and error envelope level: 


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

The notable Groq-specific differences are around its low-latency inference characteristics — extra error codes for queue saturation and rate limits are routed to MODEL_OVERLOADED so consumers with a fallback chain treat them like other transient backpressure signals.

Status mappings:

  • rate_limit_exceeded / requests_too_many → MODEL_OVERLOADED
  • model_not_found → MODEL_NOT_FOUND
  • context_length_exceeded → CONTEXT_TOO_LONG
  • invalid_api_key / authentication_error → AUTHENTICATION_FAILED
  • invalid_request_error → INVALID_REQUEST
  • HTTP fallback for unrecognised codes

Captured headers: retry-after, x-ratelimit-*, x-request-id, groq-region (Groq surfaces the datacentre handling each request — useful for routing-issue triage).

Since:
0.5.3 (issue #87 follow-up — seventh pilot mapper)

      public GroqProviderErrorMapper()

  • 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
