Hi @Ankit_Patnaik,
Welcome to the MongoDB Community forums ![]()
The usage of callback functions has been deprecated in Mongoose 7.x. Therefore, if you were using these functions with callbacks, it is recommended to use either async/await or promises. If async functions do not meet your requirements, you can go for promises.
// Before
conn.startSession(function(err, session) {
// ...
});
// After
const session = await conn.startSession();
// Or:
conn.startSession().then(sesson => { /* ... */ });
I hope it helps!
Best,
Kushagra
