Error description

  • HTTP POST is coming into HTTP server adapter with XML data that
    starts with a $, which is an invalid XML character. The HTTP
    Server Adapter with a URI calls a custom Business Process.
    The payload of the Trading Partner's messages begin with:
    %$xmldata. It uses as one of its HTTP headers in the POST:
    Content-Type: application/x-www-form-urlencoded;charset=utf-8
    
    When the Trading Partner's message hits the HTTP Server
    adapter, an HTTP 500 message is returned, and the Business
    Process does not get kicked off.
    The HTTP log contains errors:
    [2018-07-09 09:55:53.723] ERROR PSHttpServletHandler.invokeBP()
    - Exception while trying to invoke Business Process
    [EAM_BP_InboundXML]:
    INVALID_CHARACTER_ERR: An invalid or illegal XML character is
    specified.
    [2018-07-09 09:55:53.723] ERROR [1531144553723]
    INVALID_CHARACTER_ERR: An invalid or illegal XML character is
    specified.
    [2018-07-09 09:55:53.723] ERRORDTL
    [1531144553723]org.w3c.dom.DOMException: INVALID_CHARACTER_ERR:
    An invalid or illegal XML character is specified.
    

Local fix

  • RTC ID: 572575
    LB / NM
    Circumvention:
    1. Remove invalid characters from payload data.
    2. Try changing the Content-Type from
    application/x-www-form-urlencoded;charset=utf-8 to some other
    value such text/plain
