ClientSession cannot be serialized to BSON - Mongodb Transaction - node.js

Question

I'm fairly new to mongodb transaction so I have no idea what I did wrong. I've followed the direction in the documentation but I still get this error
{
"status": 400,
"name": "Error",
"message": "ClientSession cannot be serialized to BSON."
}
Here's my code
async createInsurance(params) {
const session = await db99.startSession();
try {
session.startTransaction();
const doc = await db.insurance
.find({ session })
.sort({ createdAt: -1 })
.limit(1)
.lean();
const latest = doc[0];
const payload = { ...params, id: latest ? latest.id + 1 : 1 };
const data = await db.insurance.create(payload, { session });
await mongoTransaction.commitWithRetry(session);
const result = defaultResult('SuccessCreateInsurance', SuccessCreateInsurance[this.lang], data, 200);
return result;
} catch (error) {
logger.log('error', 'ProductService-createInsurance', { error });
throw error;
} finally {
await session.endSession();
}
}
Is there anything I missed?

Answer 1

The documentation for Model.create indicates that the documents must be passed in an array in order to specify options:
[options] «Object» Options passed down to save(). To specify options, docs must be an array, not a spread.
Change
const payload = { ...params, id: latest ? latest.id + 1 : 1 };
to
const payload = [{ ...params, id: latest ? latest.id + 1 : 1 }];

turns out I have to pass session on the 3rd parameter on find method and wrap payload as an array on create method cause it can only take an array.
the code will look like this
async createInsurance(params) {
const session = await db99.startSession();
session.startTransaction();
try {
const doc = await db.insurance
.findOne(null, null, { session })
.sort({ createdAt: -1 })
.limit(1)
.lean();
const latest = doc[0];
const payload = { ...params, id: latest ? latest.id + 1 : 1 };
const data = await db.insurance.create([payload], { session });
await session.commitTransaction();
const result = defaultResult('SuccessCreateInsurance', SuccessCreateInsurance[this.lang], data, 200);
return result;
} catch (error) {
await session.abortTransaction();
logger.log('error', 'ProductService-createInsurance', { error });
throw error;
} finally {
await session.endSession();
}
}
