Hi,

the reported behavior is due to a limitation of the Community WebRatio Platform. With the WebRatio Professional platform you can generate and debug your Data Service Project on the local machine instead of the remote Cloud space.

In order to better understand how to configure the database connection with MySQL hosted on the Cloud space you can refer to this guide: https://my.webratio.com/learn/learningobject/webratio-cloud-dashboard-user-guide.
