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.

我认为您如何使用创建方式存在问题，或者至少这是我的第一个猜测。

要指定选项，文档必须是数组，而不是点差。

https://mongoosejs.com/docs/api.html#model_Model.create

必须采用这种形式

Model.create([doc], options)

你有

Model.create(doc, options)

这可能就是您想要的

let [commission] = await commissionModel.create([{datetime: Date.now(), 
...}], {session})

let [commission] = await commissionModel.create([doc], options})

当您将数组传递给Model.create（）时，Model.create（）将返回一个包含您创建/保存的文档的数组，因此这就是为什么我使用“ let [commission]”（将[commission]）设置为第一个变量返回数组中的项。
