Weird exception in background

[JornWildt]

Once in a while I get this exception after a MVC controller has completed, on a page with no editor in it:

This exception was originally thrown at this call stack:
    [External Code]
    AspNetCore._Admin_Modules_VisualEditor_MVC_Views_Frame.ExecuteAsync.AnonymousMethod__1() in Frame.cshtml

fail: Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[1]
      An unhandled exception has occurred while executing the request.

The user ID 5 is not the currently signed-in user (which is user ID 6).

I am experimenting with user sign-in so there may very well be something wrong with user ID 5 ... but what happens here? The issue only shows in the log and not in the browser.

I expect this is related to #530, whereby one of your user accounts does not have role access permissions. Bear in mind that if you have multiple user areas, it is possible to be logged into both areas at the same time. So if user 5 and 6 are from different user areas, it is possible to be logged in at the same time. More info in the docs for the ambient user area.

Either way I'll have to look into it. As mentioned in #530 it might be that a better exception message can be thrown here if it is a known configuration error.
