Hi,

i am trying to migrate a project from RAP 1.5.1. to latest version RAP 2.3. I created a new workspace and setup a target environment and imported the project into the new workspace.
After fixing the compiler errors and other things explained in the migration guide I tried to start the application but I am getting the error like below. Does anyone have an idea how to fix this?

Regards Bertin

Hi,
is your application workbench based? This error happens when you have 2
applications registered on the same path. Please check that no rap demo
bundles are included in the launch config. If your application is not
workbech based, make sure that rap.workbench bundle is also not selected.
HTH,
Ivan
