CAUSE

The issue was caused by the files for the currently deployed application being removed/deleted from the repository where Apprenda stores them.

RESOLUTION

There are two potential solutions to the issue based on the application architecture.

If the Application does NOT have an Apprenda deployed database, then simply deleting the application and recreating it will solve the issue.
If the Application does have an Apprenda deployed database, you will need to retrieve the deleted files and recreate the required structure.
If the removed files are not available contact the Apprenda Support team for other ways to recreate them.
