I get an error when I try add data to Firestore

[Jawad Talebi]

Hello all!

I got these when I try to add data to FIrestore. My app does not crash, and my Firebase Authentication works perfectly. 

W/System: Ignoring header X-Firebase-Locale because its value was null.

I got the same error for Firebase Authentication, and then I changed my emulator version and it worked. I don't know what to do with Firestore. I would appreciate any help. Thanks!
