Using Perl I get error 400 Invalid request when Posting item belong to DDS service which is an AT...

...S Service

Hi,

I Use the Perl example from the GitHub, I try to Post data of a specific RIC, i changed only the ric name, host name, user name and added "Service" = "DDS" to the post message part, all is flowing great until the post, the login is working, when I send the request i get the stream is open, but i get 400 Invalid request as response to the post

this is what I send in the post

encode_json({ "ID" => 2, 
              "Type" => "Post",  
              "Domain" => "MarketPrice", 
              "Ack" => JSON::true,  
              "PostID" =>  1, 
              "PostUserInfo" => { "Address" => $position, "UserID" => Int($$)  },
              "Message" => { "ID" => 0, "Type" => "Update", "Domain" => "MarketPrice",
                             "Fields" => {'BID' => 45.55, 'BIDSIZE' => 18, 
                                           'ASK' => 45.57, 'ASKSIZE' => 19}  } });

and I get

{
     'NakCode' => 'DeniedBySrc',
     'ID' => 2,
     'Type' => 'Ack',
     'Text' => '[400]: Invalid Request',
     'AckID' => 1,
     'Key' => {
             'Service' => 'DDS',
             'Name' => 'MO=FIBP'
     }
}

any Idea's what I am doing wrong ?
