NoMethodError: undefined method `first' for "json":String
Description
Cause:
config validation wasn't yielding strings for ":validate => :string' config properties, it was doing a single-element array, I guess. It doesn't do that anymore, so now if you specify 'format' the code tries 'format.first' which fails on a string.
