Hi SAP team

I'm trying to take a view from last openSAP course and after follow the release steps to get this project an error happens when activate BulletinBoardItem.bo

With solutions created from May 2019, you are no longer allowed to use Text data type. We recommend that you use the String data type in the http://sap.com/xi/AP/PDI/bo namespace or text data types of limited length

Affected fields: Title, Location, Description

If I try to solve it changing to types LONG_Name, String, LONG_Description respectively, it also doesn't work. In desktop client a blank screen is rendered and in the mobile client a RABAX post dump error happens
