Updated __proto__

[SteeveGL]

I casting an object and I got an updated __proto__

const customerDiff: any = detailedDiff(this.customer, this.form.value as Customer);

{
  __proto__:Object {...}
}

Can I ignore it?

All properties present in the diff come from the input objects; to this module, __proto__ is just another property. It must have been set by some other code.

Can you post the results of the following?

Object.prototype.hasOwnProperty.call(this.customer, '__proto__')
Object.prototype.hasOwnProperty.call(this.form.value, '__proto__')
Object.prototype.hasOwnProperty.call(customerDiff, '__proto__')

console.log('this.customer', Object.prototype.hasOwnProperty.call(this.customer, '__proto__'));
console.log('this.form.value', Object.prototype.hasOwnProperty.call(this.form.value, '__proto__'));
console.log('customerDiff', Object.prototype.hasOwnProperty.call(customerDiff, '__proto__'));

this.customer false
this.form.value false
customerDiff false

Going to close as I can't reproduce this myself but feel free to re-open or to share more details to repro the error.
