When I try to send an MMS message I get:
{ "errorCode" : "InvalidParameter", "message" : "Parameter [attachments] value is invalid.", "errors" : [ { "errorCode" : "CMN-101", "message" : "Parameter [attachments] value is invalid.", "parameterName" : "attachments" } ], "parameterName" : "attachments" }
Does anyone know what's wrong? I have the JSON formatted properly and it worked in the sandbox. Now it does not work in production.
