Class ReplicateProviderErrorMapper

java.lang.Object
com.tnsai.llm.errors.ReplicateProviderErrorMapper
All Implemented Interfaces:
ProviderErrorMapper
public class ReplicateProviderErrorMapper extends Object implements ProviderErrorMapper
ProviderErrorMapper for Replicate. Replicate's HTTP API is built on a FastAPI-style stack, so non-2xx responses carry a detail string (occasionally a title/detail/status triple): 

 { "detail": "Invalid token." }

(A failed prediction on a 2xx response instead surfaces an error string on the prediction object — that path is handled by the client when it inspects the prediction status, not by this mapper, which only sees HTTP error responses.)

Replicate does not expose a stable native error-code enum, so the LLMException.ErrorType is derived from the HTTP status (429 → overloaded, 5xx → server error, 401/403 → auth) and the detail message is surfaced for observability.

Since:
0.12.0 (TNS-622)

  • Constructor Details

    • ReplicateProviderErrorMapper

      public ReplicateProviderErrorMapper()

  • 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
