• SAP Error Message:

  Cause
  This error typically occurs in the context of SAP PI/PO (Process Integration / Process Orchestration) or when dealing with proxy communication in SAP systems. The message indicates that the system encountered a data type or serialization format that it does not support.
  
  TypeCode=1 refers to the primitive data type in the SAP proxy runtime.
  The error means that the proxy runtime expects only primitive types (TypeCode=1) but received a complex or unsupported type.

  It can also occur if the message payload or the data type used in the proxy is not aligned with the expected format, e.g., trying to send a complex object where only primitive types are allowed.
