I was able to solve this error by changing the appengine-web.xml.

Now I am getting this error

Unable to update: Error posting to URL:
403 Forbidden
You do not have permission to modify this app (app_id=u's~driven-copilot-143702').

To solve it, you would need to run the cmd. Go to start and run cmd.

Navigate to C:\appengine-java-sdk-1.9.17\bin or whichever your appengine location is then type:

appcfg update "C:/path/to/app/directory/"
