Is that all it says? Is there no stack trace? If there is show us
the complete error and stack trace (either from the test or from the
website itself), and the code around where the error is generated.
Presumably there is a redirect call there, look closely at it to see
why it might be trying to redirect to nil.

That says the error is occurring in your code at line 50. Perhaps it
would be useful if you posted that area of your code so that we can
see it. Probably best to post the whole of the create method. First
though, as I suggested in my previous post, look carefully at that
code and see if you can see why it might be trying to redirect to nil.
