Error Cause​

Database write failed, duplicate index key, such as inserting data with the same _id.

Solutions​

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