Hi Everyone, Any one faced this issue while creating a new app in Mendix 9.0.2 beta version. I have tried to create a new app by clicking new app from the modeler but I am this error.
Do note that 9.0.2 is still Beta. You model was created after the release of 9.0.2 and thus can not be opened. Either wait for a new beta or final release. Then this will be solved. I would only use the beta version for new test projects to check out the new functionality.
This is how it worked for me on v9.0.2.
Delete all apps(lower versions) created by you from Developer Portal.
