Error description

  • If a SOAP Input node is configured to use HTTP Basic
    authentication but receives a malformed authentication token
    that is not a valid base64 string will result in the client
    receiving a timeout fault response rather than a HTTP 400 - Bad
    Request response.
    
    Syslog entries indicative of this problem are
    
    (Msg 1/3) BIP2628W: Exception condition detected on input node
    'SOAPInputNode'.
    
    (Msg 2/3) BIP3748E: The SOAP Input node 'MsgFlow.SOAPInputNode'
    encountered an error while processing the inbound SOAP message.
    
    (Msg 3/3) BIP4019E: Error decoding (converting) the base64
    character string 'AUTH_TOKEN' to a BLOB. State = '-1' 'S22018'
    '0' ''.
