This is probably due to your fingerprint not being added to the android app on Firebase. Supply someone in the team that has Firebase access with your SHA-1.

Follow the following instructions to find your SHA1 key.

Note: You need to have Java installed.

macOS

• Run keytool -list -v -alias androiddebugkey -keystore ~/.android/debug.keystore
• Enter the default password android
• Copy Certificate fingerprint: SHA1: <YOUR SHA1>

Windows

• Navigate to the android folder situated inside the project folder. For example: cd C:\Users\Root\Documents\Development\projects\dibbs\android
• Run .\gradlew.bat signinReport
• Copy the SHA1: <YOUR SHA1> under debugUnitTest
