Hello, Tirgei.
How are you?
I downloaded your app to learn more about firestore and to learn how to use fragments. The project is great and I started to explore it but I have a doubt...
When I book a test drive or when I place an order, nothing happens in firebase and I cannot see anything like a booking or order in the account where I posted the car/part.
I see the next errors:
E/PartActivity$makeOrder: RESULTS: Error: could not handle the request

E/CarActivity$book: RESULTS: {"booker_id":"RQWcPYHuRtSgR7pkH6Q1czEaGvN2","resultCode":0,"description":"Booking created succesfully","seller":"Mario Sandoval"}

These are my rules on firebase:
Realtime Database:
{ "rules": { ".read": "auth != null", ".write": "auth != null" } }

Firestore:
service cloud.firestore { match /databases/{database}/documents { match /{document=**} { allow read, write; } } }

How do you solve it? Do you have the same issue? I have not modified the code, I just added the .json archive
I hope you can help me.
