I am beginner in Google Cloud platform, I deployed my java web application using NetBeans 8.2 and i follow the tutorial on this link(https://blog.idrsolutions.com/2015/09/how-to-use-the-google-app-engine-with-the-netbeans-ide/). When i run the appengine and login to a form, it returns:
"Error: Server Error
The server encountered an error and could not complete your request. Please try again in 30 seconds."
when i check the error in Error Reporting in Google Cloud Platform:
