FirebaseRemoteConfigFetchException when fetching Remote Config

Using GMS and Firebase 9.0.2

I set up my app with Firebase, features like Analytics or Notifications are already working. Now I tried to add Remote Config but every time I call fetch, I get a com.google.firebase.remoteconfig.FirebaseRemoteConfigFetchException.

I’m not doing anything special. Basicly, all I do is

FirebaseRemoteConfig.getInstance().fetch().addOnCompleteListener {
    toast(it.isSuccessful.toString())
    it.exception?.printStackTrace()
}

in my main activity’s onCreate method (nevermind the Kotlin syntax) and every time I get

com.google.firebase.remoteconfig.FirebaseRemoteConfigFetchException
  at com.google.firebase.remoteconfig.FirebaseRemoteConfig.zza(Unknown Source)
  at com.google.firebase.remoteconfig.FirebaseRemoteConfig$1.zza(Unknown Source)

I am having the exact same problem. This issue was closed with problems still existing it seems. Is anyone still having this problem? Has anyone figured out how to resolve it?

I’m still getting this issue as well, using 10.2.0 Always comes back with a fetch exception with no detail message. Makes no difference whether I use a cache expiration parameter or not in the fetch call.
