I have a question about to insert object in firestore in angularfire:
My object Person.ts
name: String
age: Number
//--constructor--
//--getters and setters--
if I do this, insert ok: (BUT is this good practice?)
[person.component.ts]
      this.db.collection("person").add({
              name: this.person.$nome,
              age: this.person.$email
          })
    ...
but if I try:
    [person.component.ts]
         this.db.collection("person").add({
                     Person: this.person
//or this this.person
                  })
I get this error in browser console:
Function DocumentReference.set() called with invalid data. Unsupported field value: a custom Person object (found in field Person) at new FirestoreError (error.js:149) at
