[SOLVED] Firebase Functions NOT_FOUND for europe regions

Firebase Functions NOT_FOUND for europe regions

I have tried to create an function in europe-central2 region. Unfortunately, I got this error if the function is not in the default region when calling from the Kotlin sdk:

return Firebase.functions.httpsCallable("returnDistricts").invoke().data<String>()

FATAL EXCEPTION: main
Process: com.app.afterfood.android, PID: 6689
   com.google.firebase.functions.FirebaseFunctionsException: NOT_FOUND at com.google.firebase.functions.FirebaseFunctions$2.onResponse(FirebaseFunctions.java:388)

It works perfect if it is in default region: us-central1.

Any idea if it is possible to call a function that is not in the default region?

Solution

This is covered in the documentation:

Note: To call a function running in any location other than the default us-central1, you must set the appropriate value at initialization. For example, on Android you would initialize with getInstance(FirebaseApp app, String region).

This means you will need to need to get a FirebaseFunctions instance using getInstance, passing the region to use for that FirebaseApp instance in the second paramter.

Firebase.functions
    .getInstance(/* your region params */)
    .httpsCallable(...)
