TypeError: 'set' on proxy: trap returned falsish for property

[asystat]

Hello, I am trying to create a simple relation but I am getting this very uninformative error.

This is the code:

    let car = db.R.dispense('car');
    car.brand = 'Brand';
    car.model = 'Model';
    car.year = 'Model';
    car.chat_keyword= 'KWD';
    try {await db.R.store(car);}catch (e) {console.log(e);}

    console.log("Creating usercar model");
    let usercar = db.R.dispense('usercar');
    usercar.added_date = db.R.isoDate();
    usercar.car = car;
    try {await db.R.store(usercar);}catch (e) {console.log(e);}

Error:

TypeError: 'set' on proxy: trap returned falsish for property 'carId'

Am I doing something wrong? thx

Thank you for trying the library.

After some investigations, it turns out it is a bug of "Magic Methods"
https://gist.github.com/loilo/4d385d64e2b8552dcc12a0f5126b6df8

 instanceHandler.set = (target, name, value, receiver) => {
    if (name in target) {
      Reflect.set(target, name, value, receiver)     // Bug here, it does not return anything!
    } else {
      return target.__set.call(target, name, value)
    }
  }

Will be fixed in the next version.
At this moment, you can remove this call "await db.R.store(car);" which you can bypass this error
