Grammarly Common Errors

Error Reference

400 Bad Request — Text Too Short

Cause: Text has fewer than 30 words. Fix: Ensure minimum 30 words. Pad short texts with context if needed.

401 Unauthorized

Cause: Token expired or invalid. Fix: Re-authenticate with client credentials grant.

413 Payload Too Large

Cause: Text exceeds 100,000 characters or 4 MB. Fix: Split into chunks using paragraph boundaries. See grammarly-sdk-patterns for chunking function.

429 Too Many Requests

Cause: Rate limit exceeded. Fix: Implement exponential backoff. See grammarly-rate-limits.

Plagiarism Check Stuck on "pending"

Cause: Large document processing or service delay. Fix: Poll every 3-5 seconds, timeout after 90 seconds.

AI Detection — Inconsistent Scores

Cause: Short text produces unreliable results. Fix: AI detection works best on 200+ words. Scores on short text are less reliable.
