              Specify the config file using the EXEC_APP_CONFIG argument. e.g.

              Alternately, specify a service name directly with EXEC_SERVICE_NAME. e.g.

              Could not determine which service should run this command because the App
              Engine config file "#{e.config_path}" was malformed.
              It must be a valid YAML file.
              Specify the config file using the EXEC_APP_CONFIG argument. e.g.
                bundle exec rake serverless:exec EXEC_APP_CONFIG=myapp.yaml -- myscript.sh
              Alternately, specify a service name directly with EXEC_SERVICE_NAME. e.g.

                Please double-check the version exists. To use the most recent version by
                default, omit the EXEC_APP_VERSION argument.

                Could not find any versions of service "#{e.service}".
                Please double-check that you have deployed this service. If you want to run
                a command against a different service, you may provide a EXEC_APP_CONFIG
                argument pointing to your App Engine config file, or a EXEC_SERVICE_NAME
                argument to specify a service directly.

                gcloud config set project my-project-id
              or specify the project by setting the EXEC_PROJECT argument. e.g.
