Mongoose create on session fails on validation - mongodb

Question

I am trying to create a document, on an existing collection, using MongoDB + async..await programming + session/transaction control (in order to be able to rollback to a previous state if anything goes wrong). The relevant code is shown below:
exports.campaign_totalize = async (campaign, start_date, end_date, now) => {
var session = await mongoose.startSession();
session.startTransaction();
try {
// ...
let commission = await commissionModel.create({
datetime: Date.now(),
value: 10,
status: 'issued',
affiliate: affiliate_id,
campaign: campaign_id
}, { session: session });
// ...
}
// ...
} catch (err) {
console.log("Error totalizing commissions:", err);
await session.abortTransaction();
session.endSession();
throw err;
}
}
Executing code above I get ValidationError on ALL fields (even being sure they are all OK). If I remove the session parameter, however, everything works fine! The collections exists for sure.
Below information about my environment:
"dependencies": {
"express": "^4.16.4",
"mongoose": "^5.3.9",
"mongoose-bcrypt": "^1.6.0",
"validator": "^10.9.0"
}
$ node --version
v10.14.0
$ mongod --version
db version (v3.6.3) -> v4.0.4
Thank you very much.
Update:
As Shivam Pandey pointed out in the comments, mongoDB version starts supporting transactions on version 4.0. I just updated it to 4.0.4 and it is returning the same errors, though.
Update 2:

Answer 1

I think there's an issue with how you're using the create, or at least that's my first guess.
To specify options, docs must be an array, not a spread.
https://mongoosejs.com/docs/api.html#model_Model.create
Has to be in this form
Model.create([doc], options)
you have
Model.create(doc, options)
This might be what you want
let [commission] = await commissionModel.create([{datetime: Date.now(),
...}], {session})
let [commission] = await commissionModel.create([doc], options})
When you pass an array into Model.create(), Model.create() will return an array with the documents you created/saved so that's why I used "let [commission]" which will set variable commission to the first item in the array that gets returned.
