Answer 1

The error is happening because it is not possible to call the create function on the "supported" attribute of the User object. What you can do is create a static function that takes the data as a parameter and does something when the function is called, like this:

userSchema.statics.createSupported = function(data: any) {
     // do something here..
}

userSchema.statics.createSupporting = function(data: any) {
     // do something here..
}

And when you call the query:

const requester = await User.findOne({ _id })
const supporter = await User.findOne({ _id: _idSuporter })
// Result ok
User.createSupported(date)
User.createSupporting(data)
