I want to upgrade my project from 5.18.0 to 5.21.0, however when I try to convert my local project, or download it from the repository i get the following error at step 'update original project file', not the 'convert project' step. System.NullReferenceException: Object reference not set to an instance of an object. at Mendix.Modeler.Integration.ConvertLocalizedContentsAndLocation.Convert(IProject project) in c:\jenkins\workspace\AppStudio-Integration-Modeler\src\modeler\Mendix.Modeler.Integration\Conversions\ConvertLocalizedContentsAndLocation.cs:line 29 at

tell the cause is the same. Problem is that I don't know what the cause is. Can anyone offer a solution? EDIT: In the release notes there's the part that says: Known issues Converting a project with duplicate Role-based home pages causes an exception. A workaround is possible by removing the duplicates before converting. First of all, we don't have any duplicate role-base home pages (each role appears only once in the list). Also removing all of these and then converting still gives me the same exception. EDIT 2: I removed all the widget MPKs from the Widget folders and then tried to upgrade, no luck I created a branch from a tagged version from many sprints ago, also no luck
