Overview

Package errors provides rich error context for AI provider operations. It includes request/response snapshots, timing information, correlation IDs, and credential masking for secure debugging and tracing.

Package errors provides rich error context for AI provider operations.

This package implements comprehensive error handling with debugging context, including request/response snapshots, timing information, correlation IDs, and automatic credential masking for secure logging and tracing.

Overview

The errors package provides four main components:

  1. Error Context - Structured context information about errors
  2. Credential Masking - Security-focused masking of sensitive data
  3. Rich Errors - Error wrappers with full context
  4. Middleware - Automatic error context capture

Error Context

ErrorContext captures detailed information about when and where an error occurred: 

ctx := errors.NewErrorContext().
    WithRequestID("req-123").
    WithCorrelationID("corr-456").
    WithProvider(types.ProviderTypeAnthropic).
    WithModel("claude-3-opus").
    WithOperation("chat_completion").
    WithDuration(150 * time.Millisecond)

Request and response snapshots can be captured automatically: 

config := errors.DefaultSnapshotConfig()
reqSnapshot := errors.NewRequestSnapshot(httpRequest, config)
respSnapshot := errors.NewResponseSnapshot(httpResponse, config)

Credential Masking

The package provides automatic masking of sensitive information in logs: 

masker := errors.DefaultCredentialMasker()
safe := masker.MaskString(`{"api_key": "secret123"}`)
// Result: {"api_key": "***MASKED***"}

Headers are automatically masked: 

safeHeaders := masker.MaskHeaders(req.Header)

Custom patterns can be added: 

masker.AddPattern(
    regexp.MustCompile(`session_id=([A-Za-z0-9]+)`),
    "session_id=***MASKED***",
)

Rich Errors

RichError wraps errors with comprehensive context: 

err := doAPICall()
if err != nil {
    richErr := errors.Wrap(err).
        WithRequestID(requestID).
        WithProvider(types.ProviderTypeOpenAI).
        WithModel("gpt-4").
        WithRequestSnapshot(req).
        WithResponseSnapshot(resp).
        WithTimingStart(startTime)

    // Get formatted output for logging
    log.Error(richErr.Format())

    return richErr
}

Rich errors maintain the error chain and work with errors.Is/As: 

if errors.Is(richErr, context.DeadlineExceeded) {
    // Handle timeout
}

Middleware Integration

The package provides middleware for automatic error context capture: 

config := errors.DefaultErrorContextMiddlewareConfig(types.ProviderTypeAnthropic)
errorMw := errors.NewErrorContextMiddleware(config)

chain := middleware.NewMiddlewareChain()
chain.Add(errorMw)

// Use with HTTP requests
ctx, req, err := chain.ProcessRequest(ctx, req)
// ... perform request ...
ctx, resp, err := chain.ProcessResponse(ctx, req, resp)

// Retrieve error context
if err != nil {
    errCtx := errors.GetErrorContext(ctx)
    enrichedErr := errors.EnrichError(ctx, err)
    log.Error(enrichedErr)
}

Correlation Tracking

For simpler correlation tracking without full error context: 

corrMw := errors.NewCorrelationMiddleware("X-Correlation-ID", true)
chain.Add(corrMw)

// Later, retrieve the correlation ID
correlationID := errors.GetCorrelationID(ctx)

Security Considerations

The package is designed with security in mind:

  • Sensitive headers (Authorization, API keys, etc.) are automatically masked
  • Request/response bodies are scanned for credentials and masked
  • Body size is limited to prevent memory issues
  • Custom masking patterns can be added for domain-specific secrets

Configuration

Snapshot capture can be configured: 

config := &errors.SnapshotConfig{
    MaxBodySize:    8192,              // Capture up to 8KB
    IncludeHeaders: true,              // Include headers
    IncludeBody:    true,              // Include body
    Masker:         myCustomMasker,    // Custom masker
}

richErr := errors.NewRichErrorWithConfig(err, config)

    if err != nil {
        return nil, errors.Wrap(err).
            WithProvider(types.ProviderType(p.Name())).
            WithOperation("chat_completion").
            WithModel(req.Model)
    }

            WithRequestSnapshot(httpReq).
            WithTimingStart(startTime)
    }
    defer httpResp.Body.Close()
