Fix Error with AI Tool

Error Cause​

Database write failed, index key duplicate, for example inserting data with same _id.

Solution​

  1. Check if attempting to insert duplicate _id
  2. Use upsert operation instead of insert
  3. Query if same data already exists before inserting
  4. Check if unique index fields have duplicate values
  5. Use database update operation instead of insert operation
