How to solve Circular dependency error in nodejs?

Question

I am executing the following code inside a post request:

try{
  const _id = await db.collection('UserInformation').insertOne(userObj);
  await db.collection('LoggedInUser').updateOne({ userId: _id }, { '$set': { 
  'isLoggedIn': true } }, { upsert: true });  
}
catch(e){
  console.log(e);
}

and I am getting the circular dependency error.

When I comment out the following line, everything works fine.

await db.collection('LoggedInUser').updateOne({ userId: _id }, { '$set': { 
  'isLoggedIn': true } }, { upsert: true });

Kindly let me know what may be the issue here and how to rectify it.

The function insertOne() doesn't return an _id, it returns a InsertOneWriteOpResult. This has a connection field which will likely have circular references.

Use insertedId from the result object instead of the whole object itself.
