Resource not found error...

I'm making a plugin right now, but when I tried to test it, Nova came up with this:
"Error! ID 406 = resource not found"...
I understand everything except for "resource not found"
what does "resource not found" mean? Nova knew that it was ID 406, so why doens't Nova find the resource?

PS: ID 406 is a "shan" resource

Make sure that shän resource contains valid data - Nova can blork even if a resource is there if the resource contains empty fields. This particularly applies to shäns.
