SAP PO 7.5 mapping issue of REST to ABAP

[former_member427355]

Hello PI experts,

I am trying the PI REST Adapter to exposing an ABAP module (BAPI_CUSTOMER_GETDETAIL2) to a REST service. In the message mapping part, I implemented an UDF method to map the REST dynamic parameters to BAPI request. Mapping relationship as following:

Detailed mapping method getASMA():

However, during the mapping testing, an issue happened.

Runtime exception when processing target-field mapping /ns1:BAPI_CUSTOMER_GETDETAIL2/CUSTOMERNO; root message: Exception:[java.lang.NullPointerException: while trying to invoke the method com.sap.aii.mapping.api.DynamicConfiguration.get(com.sap.aii.mapping.api.DynamicConfigurationKey) of a null object loaded from a local variable at slot 5] in class com.sap.xi.tf._MM_JsonSendReq_ method getASMA[http://****.com/RestClient/011/JsonSend, id_part, com.sap.aii.mappingtool.tf7.rt.Context@6ca88852]
See error logs for details：
