Function DocumentReference.set() called with invalid data. Unsupported field value: a custom Budget object

Question

Below code works fine until today. But I don\'t know now it is not working and gives below error.Could you tell me why?

Error: Function DocumentRefere

Answer 1

Error is simply stating that data entered is invalid!

I've also faced the error from nowhere, which was because I removed the input field from interface which was supposed to get it's value and upload it in the document of some collection!

note: check your code in .ts file firebase.firestore().collection("some_name").add() / set() if some unnecessary field is there or not.
