The error message you're encountering is from MongoDB, specifically a `MongoBulkWriteException`. This exception is thrown when one or more write errors occur during a bulk operation (insert/update/delete multiple documents at once). In your case, the error details are: `BulkWriteError{index=0, code=11000, message='E11000 duplicate key error collection: imlaw_analyst.qtf_test_question index: _id_ dup key: { : ObjectId('65d41c36f57700003b004d21') }', details={ }}` This indicates that there's a 'duplicate key error' on the collection `imlaw_analyst.qtf_test_question`. The `_id` field in MongoDB is a unique identifier for each document in a collection by default. It seems like you tried to insert a new document with an `_id` value (`ObjectId('65d41c36f57700003b004d21')`) that already exists in the `qtf_test_question` collection, hence the violation of the unique constraint. To resolve this issue: - Ensure that you're not attempting to insert a document with an `_id` that has already been used. - If you're programmatically generating `_id`s and don't care about specific values, let MongoDB auto-generate them by not including the `_id` field in your insert operations. - If you're importing data and these `_id`s are coming from another source, consider either: - Transforming the data to use unique `_id`s. - Modifying your schema to not enforce uniqueness on `_id` if it doesn't need to be unique for your use case (although this is generally discouraged). - Using a different unique index for your collection if the duplicate key isn't supposed to be `_id`.
