debugging lwrp resources with shef

I try to debug my lwrp resource with shef.
Let's say a have lwrp resource named "foo_application" defined in cookbook named "foo" :

foo_application "resource name" do
end

I try to debug it with shef and fail to do that:

$ shef -z
chef > echo off
chef > cookbooks.show "foo"
(cookbook loaded okay)
chef > recipe
chef:recipe > foo_application "resource name" do
chef:recipe > end
NoMethodError: undefined method `foo_application' for #<Chef::Recipe:0x7fe1bea268c0>

I found workaround for the issue above, but I guess it's not proper approuch
