Error Cause​

When creating collection, collection already exists, cannot create duplicate collection with same name.

Solution​

  1. Use a different collection name
  2. Check if collection with same name already exists
  3. If you need to recreate, delete existing collection first
  4. Directly use existing collection instead of creating new one
  5. Add prefix or suffix to collection name to ensure uniqueness
