Dear Friends,
I have created a BDM and a very simple process to create instances of my business data.
When I start the process the instance is created successfully and I’m able to visit the instance data in the database BUT when I try to query on that data using BDM API with the following URL:
http://localhost:8080/bonita/API/bdm/businessData/com.company.model.TestBDM/1
I get the following error:
{“exception”:“class org.bonitasoft.engine.exception.BonitaRuntimeException”,“message”:“USERNAME=user1 | java.lang.NullPointerException”}
I get this error on my PRODUCTION server where I have deployed Bonita Server on Wildfly and SQL Server.
here is the server log file trace:
