I am experiencing strange errors in my new Vaadin 13 App. I have built the App structurally the same as one of my previous Vaadin 13 Applications, in which I do not experience following error.
I have 2 Views, which both have the same parent layout MainView. The MainView does not add any component but it imports some css and also checks if the user is allowed on the requested view.
The Problem is when I open View A and click on a RouterLink to go to View B, then the error occurs and View B is not displayed. Instead, I get this error message and stack trace:
There was an exception while trying to navigate to 'ViewB' with the exception message 'Not in the list'
java.lang.IllegalArgumentException: Not in the list

What confuses me is that in my previous App this worked with no problems. And there is no line in the stacktrace that points to my own code.
When I navigate from View A to View B by manually entering the URL of view B, it works fine.
What am I doing wrong? Why does this happen only in one of two apps with the same structure?
