Getting such an error, while building the app in release mode:

> Failed to list versions for com.facebook.react:react-native.

        }
    }
}

The problem appeared without any code changes. Bintray status is major outage: https://isdown.app/integrations/bintray

Please advise, which steps do I need to perform, so I can successfully create release builds.
