Question

Get suggested invitees failed due to error code: 3

and soon after

Create invitations failed to error code: 3

What kind of error is it? Where i can find an error list?

Answer 1

In my experience, this happens when the SHA-1 signature of your app is not compatible with the Android API key specified in the Google Developer Console

If you don't care which app invites you, then you might want to consider removing app/signature restrictions. Otherwise, simply add them.
