It looks like you've got an authorization issue. Can you confirm you're connected to the Internet and that you have a valid credentials.json file?

I am facing the same issue. Did you find a way to resolve it?

@reemagadhia Did you find any way to resolve this issue? It's happening in signed release build. Help me if this issue of yours is resolved.

Dialogflow issue: Did anyone have any solution to this issue?

It's working fine with debug apk but failing with released apk.
