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

You can stringify the object and parse to object again to remove class names of the object.

const budgets = this.budgetProvider.createBudgets(JSON.parse(JSON.stringify(data.budgetList)), projectId);
