Hey @Arun_vel,

Welcome to the MongoDB Community.

The use of callback functions has been deprecated in the latest version of Mongoose (version 7.x).

Reference: Mongoose v8.2.2: Migrating to Mongoose 7

If you are using Mongoose 7.x+, please modify the functions that use a callback by switching to the Promise or async/await syntax.

If you have any further questions or concerns, feel free to ask.

Regards,
Kushagra
