Hi All,

We created a Routing address and rule to send purchase order details for external API with Bearer token authorization. But when we added XML to the Json transformer it showed this error

Ifs.Fnd.FndSystemException: Explorer: An Unhandled Exception has occurred ---> Ifs.Fnd.FndSystemException: Unexpected error while calling server method ConnectTester/TestRouteAddress ---> Ifs.Fnd.FndServerFaultException: Exception while sending data
Caused by: ifs.fnd.connect.http.InternalServerErrorException: InternalServerErrorException: 500#{"RespHeader":{"Username":null,"StatusCode":"500","ErrorMsg":"Object reference not set to an instance of an object.","TxType":null,"MessageId":null,"Timestamp":null,"Encrypted":false},"RespBody":null}
   at Ifs.Fnd.AccessProvider.FndConnection.ParseErrorHeader(FndBuffer buffer, FndManualDecisionCollection decisions)
   at Ifs.Fnd.AccessProvider.FndConnection.UnMarshalResponseHeader(Stream responseStream, FndManualDecisionCollection decisions)

same error showed in application messages also 

Can anyone why it happened? Kindly expect your answers.

Thank you
