2940375 - Error in Message Mapping Simulation


While running simulation for Message Mapping, you may get an error that contains the following message:

"The root message is: Exception:["


 SAP Cloud Platform Integration

Reproducing the Issue

  1. Open an Integration Flow in Edit mode.
  2. Open the Message Mapping step, which uses exchange properties/headers set previously.
  3. Run Message Mapping simulation.
  4. An error occurs, as mentioned in the symptom section.


The possible cause for the error is the headers/properties values set earlier is ignored during the simulation.


There are two options provided here to help you resolve when you face this error:

  • Disable the nodes which are using the exchange property/header.


  • Use integration flow simulation instead of message mapping simulation.
