Hello Samuel, Is your SDK up-to-date? You may try running the gcloud components update and then gcloud info. What is the output of this last command? Trying again gcloud.app.deploy may then succeed.
If the above steps do not fix your issue, it is worthwhile running the "gcloud config set app/use_deprecated_preparation True" command. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
