Hello, your project is great, but it is not very clear how to make it work without that problem of Firebase document not exists.

How could you help us solve the problem.

In other words, where should I upload the backEnd you have?

Excuse me but I am a newbie, and I don't know how to fix the error Firebase document not exists

This is the server, using firebase cloud function https://github.com/abdularis/Track-My-Location_Cloud-Functions
