Exception in code

[SternAndrew]

I would fix this but not yet sure where the check should be to prevent this issue. Here is the stack trace of the exception:

/home/astern/.gem/ruby/gems/viewpoint-1.0.0/lib/ews/soap/ews_response.rb:31:in `envelope': undefined method `[]' for nil:NilClass (NoMethodError)
        from /home/astern/.gem/ruby/gems/viewpoint-1.0.0/lib/ews/soap/ews_response.rb:39:in `body'

        from /home/astern/.gem/ruby/gems/viewpoint-1.0.0/lib/ews/connection.rb:74:in `dispatch'

        from /home/astern/.gem/ruby/gems/viewpoint-1.0.0/lib/ews/soap/exchange_data_services.rb:87:in `get_item'
        from /home/astern/.gem/ruby/gems/viewpoint-1.0.0/lib/ews/item_accessors.rb:33:in `get_item'

        from /cygdrive/c/Users/astern/Desktop/outlook.rb:59:in `<main>'

Here is the code path from the initialize. Its' clear that '@resp[:envelope][:elems]' is the [] on nil it is complaining about.

    def initialize(sax_hash)
      @resp = sax_hash
>>      simplify!
    end

    def simplify!
>>      response_type = response.keys.first
      response[response_type][:elems][0][:response_messages][:elems].each do |rm|
        key = rm.keys.first
        rm[key][:elems] = rm[key][:elems].inject(&:merge)
      end
    end

    def response
>>      body[0]
    end

    def body
>>      envelope[1][:body][:elems]
    end

    def envelope
>>      @resp[:envelope][:elems]
    end

I'm seeing a similar issue. Here's the stack trace:

NoMethodError: undefined method `each' for nil:NilClass
    from /app/vendor/bundle/ruby/2.3.0/bundler/gems/Viewpoint-5475b290d558/lib/ews/soap/ews_response.rb:65:in `simplify!'

The server we're looking at is Exchange version 2010.

Here's the pretty-printed response from find_items before the call to items_parser (which is the line that crashes):

#<Viewpoint::EWS::SOAP::EwsResponse:0x007f94ece8da40

                {:major_version=>"14",
