Mobius 2sxc App creation in Oqtane fails

[SSzretter]

When I add the Mobius app to a page, it throws an exception (System.NullReferenceException: 'Object reference not set to an instance of an object.') on the second field (QueryString:FirstName).

I am Using the latest version of Oqtane (5.2.1) and SQLEXPRESS, Mobius latest 6.18 , 2sxc 18. I started from a completely fresh pull of Oqtane from github.

I used these instructions to install 2sxc and successfully added the Blog app to a page and it seems to function properly: https://azing.org/2sxc/r/VJEjD7bN

I installed Mobius by creating a new page, added the App module to the page and then click on the Mobius icon at the bottom.
That is when I see the exception in VS.
