Stack overflow when calling signInWithCustomToken()

[YellowPrawn]

I'm running in to a stack overflow that seems to be related with coroutines. Does anyone have tips for any possible fixes?

It's occurs when I call FirebaseAuth.getInstance().signInWithCustomToken(). Interestingly enough, it does eventually sign into a user, but when FirebaseAuth.getInstance().signOut() and I try signing again after, it is completely unable to sign in.

Does the stacktrace repeat?

[YellowPrawn]

yep

[nbransby]

Could you send the full stacktrace then please
