I am making a CI/CD in my challenge repo utilizing github motion for my ios software, when i run it i get this error

Error (Xcode): Construct enter file can't be discovered: '/Customers/runner/Downloads/GoogleService-Information.plist'. Did you neglect to declare this file as an output of a script section or customized construct rule which produces it?
