Error message

${this.name} API error during ${operation}: ${errorMessage}

What it means

BaseAIProvider.handleError wraps any error thrown during a provider operation into a normalized Error with the pattern '<ProviderName> API error during <operation>: <original message>'. It is the single catch-path used by generateText, streamText, generateObject and streamObject, so almost any downstream failure (auth, network, bad model, SDK error) surfaces in this form.

Solutions

1. Read the trailing original message after 'API error during <operation>:' — that is the root cause
2. Log/check the underlying error: handleError already log('error', ...) with the error object
3. For auth messages, verify the provider's API key env var; for model errors, verify modelId against provider docs
4. Add retry with backoff for transient network/rate-limit messages

Example fix

// before
catch (e) { /* vague handling of wrapped error */ }
// after
catch (e) {
  if (e.message.includes('API error during generateText: 401')) {
    // fix credentials
  } else if (/429|rate/i.test(e.message)) {
    // retry with backoff
  }
}

try {
  await provider.generateText({ messages, modelId });
} catch (e) {
  const wrapped = e.message.startsWith(provider.name + ' API error during ');
  if (wrapped) {
    const rootCause = e.message.split(': ').slice(1).join(': ');
    console.error('Provider op failed:', rootCause);
    // decide retry vs abort based on rootCause (429/timeout -> retry; 401 -> fix creds)
  } else throw e;
}

When it happens

Trigger: Any exception thrown inside the try block of generateText/streamText/generateObject/streamObject: SDK client errors, network failures, invalid model IDs, API 4xx/5xx responses, or errors rethrown from validateParams/validateMessages within those methods.

Common situations: Expired or wrong API keys, rate limits (429), nonexistent model IDs after a provider renamed models, network timeouts, DNS failures, or a provider SDK throwing on malformed requests.
