Symptoms

Upon creating a new Quick App, the following error appears:

Quick App Not Created

Oops! Something went wrong and we couldn't create your Quick App. Nothing has currently been created. You can try to create your Quick App again, but if it continues failing please contact a system administrator.

Upon receiving that error, the following error is printed in the application-server.log:
