Hi,

Im having an issue when running any command from firebase-plugin, we get

NoMethodError: [!] undefined method `[]' for nil:NilClass

This is happening when the sign-in challenge is triggered, the Capcha is running ok, but sign-in challenge throws this error.

We are running
ruby 2.4.2
firebase-plugin 0.2.1
fastlane 2.62.1

NoMethodError: [!] undefined method `[]' for nil:NilClass
