deploying web application on GAE
You haven't authenticated the cloud SDK. Try running gcloud auth list. Is your email included in the credentialed accounts? If not, run glcoud auth login.
If you are listed in the credentialed accounts, then perhaps you haven't properly associated your project with your login, or you have a typo in your project name.
when I want to put my project on GAE i get this error in SDK shell:
ERROR: (gcloud.app.deploy) Permissions error fetching application [apps/responsive-my-super-app-201910]. Please make sure you are using the correct project ID and that you have permission to view applications on the project.
