I am testing configurations I have done in ID and it went all successfully but with one error stating <b>"Interface mapping not found , Runtime error
Unable to read payload from the message object"</b>
after going through some links in SDN ....
I did check the Interface mapping is active and the exact one used in the config.
and did all the chache refreshes in SXI_CACHE and Administration in te main menu of XI start page ,bbut no use.
in SM59 I checked INTEGRATION_DIRECTORY_HMI connection and I got
"Http : 500
Status Tex: Internal Server Error",
i understood from sdn links and readyness check check guide this is not a problem.
so what might be the cause?
