What is the reason for the throw of an error by the insertMany function?

edit

There could be several reasons why the insertMany function throws an error:

1. Syntax error: If the syntax of the insertMany function is incorrect, i.e., there is a typo or a missing parenthesis, it will throw an error.

2. Duplicate key error: If the documents being inserted contain duplicate values for an indexed field, the insertMany function will throw a duplicate key error.

3. Validation error: If the documents being inserted do not pass the validation rules defined for the MongoDB collection, the insertMany function will throw a validation error.

4. Permissions error: If the user does not have the required permissions to insert documents into the collection, the insertMany function will throw a permissions error.

5. Network error: If there is a network issue between the application and the MongoDB server, the insertMany function may throw a network error.
