How to use mongoose transactions with updateMany?

I am using the mongoose updateMany() method and I also want to keep it a part of transaction. The documentation shows the example of save() where I can do something like Model.save({session: mySession}) but don't really know how to use it with for example Model.updateMany()
UPDATE:
For example I have two models called SubDomain and Service and they look like this respectively:
SUB-DOMAIN
{
name: {
type: String,
required: true,
},
url: {
type: String,
required: true,
unique: true,
},
services: [
{
type: mongoose.Schema.Types.ObjectId,
ref: "Service",
},
],
user: {
type: mongoose.Schema.Types.ObjectId,
ref: "User",
},
}
SERVICE:
{
name: {
type: String,
required: true,
},
description: {
type: String,
required: true,
},
price: { type: Number },
tags: { type: Array },
packages: [
{
name: { type: String, required: true },
description: { type: String, required: true },
price: { type: Number, required: true },
},
],
map: { type: String },
isHidden: {
type: Boolean,
required: true,
default: false,
},
sortingOrder: { type: Number },
isForDomain: { type: Boolean, required: false, default: false },
isForSubDomain: { type: Boolean, required: false, default: false },
subDomains: [
{
type: mongoose.Schema.Types.ObjectId,
ref: "SubDomain",
},
],
}
Now the main field here is the services field in SubDomain and subDomains field in Service.
The complicated part😅:
Whenever the user wants to create new service, I want to $push that service's _id into the array of services of all the subDomains inside that new service
And for that, I am using the updateMany() like this:
const sess = await mongoose.startSession();
sess.startTransaction();
const newService = new Service({
_id: mongoose.Types.ObjectId(),
subDomains: req.body.subDomains
...foo
})
await SubDomain.updateMany(
{ _id: { $in: req.body.subDomains } },
{ $push: { services: newService._id } }
);
The problem starts here, of course I can do:
newService.save({session: sess})
but how do I keep my SubDomain's updateMany in the same transaction (i.e sess)
I know my example is difficult to wrap your head around but I have tried to pick a simplest example rather than copying the exact same code which would have been a lot more difficult

Issue when login and register with Facebook in Meteor

I'm trying to use Facebook to connect and register into my Meteor.js application. In my login template I put a button to do this. I call the function Meteor.loginWithFacebook() but it doesn't work... I'm guessing that Meteor try to create a new user and that it doesn't find the username information but I don't know how to manage that.
My handler to call the login :
'click #facebook-login': function(event) {
Meteor.loginWithFacebook({}, function(err){
if (err) {
throw new Meteor.Error("Facebook login failed");
Materialize.toast('Echec de connexion!', 4000);
}
else {
Router.go(Utils.pathFor('home'));
Materialize.toast('Bon retour parmis nous ' + Meteor.user().username + ' !', 5000);
}
});
}
The error I have :

Thank's for any help !

The problem is that your schema requires Meteor.users to have a username field, which they don't contain by default. You can, however, generate this field by taking their name name from the Facebook profile.
Accounts.onCreateUser(function(options, user) {
user.username = user.services.facebook.name;
return user;
});

meteor: add some value to nested documents

I'm trying to add a value to a nested schema:
groups = new SimpleSchema({
title: { type: String, optional: true },
element: { type: [elements], optional: true }
});
elements = new SimpleSchema({
description:{ type: String, optional: true },
anything: { type: String, optional: true }
});
MongoDB.attachSchema(new SimpleSchema({
title: { type: String },
slug: { type: String, unique: true },
language: { type: String, defaultValue: "en" },
group: { type: [groups], optional: true },
}));
Now I want to add just a new element-description to an existing entry in the DB. I tried this, but it doesn't work.
Uncaught Error: When the modifier option is true, validation object must have at least one operator
var newElement = {
description: 'insert this as a new element description'
};
MongoDB.update({ _id: Id }, { $push: { 'group.element': newElement }}, function(error) { if(error) console.warn(error); });
Is it correct to use 'group.element' as a $push-parameter?
Update
I forgot the index of group: $push: { 'group.0.element': newElement }
Also I have to define elements before groups in the schema.

Meteor Simple Schema - When the modifier option is true, validation object must have at least one operator

I keep getting the error: Exception while invoking method 'createUser' Error: When the modifier option is true, validation object must have at least one operator when I try to create a user. I am using meteor-simple-schema, but none of the fixes with this error have worked for me. I have tried using blackbox and optional to see where the issue is but I keep getting the same error.

My accounts.creaate user is as follows:
Accounts.createUser({
email: $('#email').val(),
password: $('#password').val(),
profile: {
games: {
game1: {
public: [],
private: []
}
}
}
});
Any ideas on how I can get this to work?

You forgot to add new SimpleSchema there in the beginning:
Schemas.UserGamesPart = new SimpleSchema({
public: {
type: [String],
defaultValue: []
},
private: {
type: [String],
defaultValue: []
}
});
Schemas.UserGames = new SimpleSchema({
game1: {
type: Schemas.UserGamesPart
}
});
Also I think your usage of the nested schemas is a little off. Only nest schemas when you need to reuse one. Creating a separate schema for UserGamesPart looks horrible. Try this instead:
Schemas.UserGames = new SimpleSchema({
game1: {
type: Object
}
'game1.public': {
type: [String],
defaultValue: []
},
'game1.private': {
type: [String],
defaultValue: []
}
});
This is shorter and easier to read.

Uncaught Error: When the modifier option is true, validation object must have at least one operator

trying to read between StackOverflow and the documentation of meteor-simple-schema but can't find a solution. I'trying to insert data in the Meteor.users collection through a form. But keep getting an error:

}
});
Meteor.users.attachSchema(Schema.User);
Many thanks.

Try this schema
Schema.User = new SimpleSchema({
email: {
type: Object
},
'email.address': {
type: String,
optional: true
},
"email.verified": {
type: Boolean,
optional: true
},
profile: {
type: Schema.UserProfile,
optional: true
},
createdAt: {
type: Date,
autoValue: function() {
if (this.isInsert) {
return new Date();
} else if (this.isUpsert) {
return {$setOnInsert: new Date()};
} else {
this.unset();
}
}
}
});
Btw if you are using account-password then this schema won't work as that package expect emails to be stored in a certain way.
