ruby - Savon raises error inside Rails app, but not inside irb -

-

i'm using savon library soap requests work. , i'm using same code within irb , rails application. when i'm running irb works should, rails generate error "no method 'to_hash' nil:nilclass" inside savon's do_request -> respond_with methods.

here's code (the same when running within irb or rails):

  # setup savon client soap requests   client = savon::client.new "http://www.webservicex.net/country.asmx?wsdl"    # test if "webservicex.net" server , running   actions = client.wsdl.soap_actions    raise "soap server down" if actions.nil? or actions.length <= 0    # country list   resp = client.request :get_countries    raise "no response countries" if resp.nil?    resp = resp[:get_countries_response][:get_countries_result]

none of exceptions risen nor code far 'pinging server' executed.

what's wrong , how fix that?

it's problem httpi gem - https://github.com/rubiii/savon/issues/163 use 0.9.1 version.
