After Migration of webdynpro BPM DC from 7.3 to 7.5, I am getting exception in BPM task

[sweetysingh]

Hello Experts,

we have Migrated WebDynpro BPM DC from 7.3 to 7.5 version. when I test BPM application, I am getting 2 exception while opening the task.

1. com.sap.tc.webdynpro.services.exceptions.ApplicationFaultException: wdDoInit: exception thrown in this user coding area

2. java.lang.NullPointerException: while trying to invoke the method com.sap.tc.cu.base.wd.contract.ps.wdp.IExternalIProcessStep.setInData(com.sap.tc.webdynpro.progmodel.api.IWDNode) of a null object loaded from local variable 'cuComponent'

I went through so many documents and tried but no luck.

I checked Service Registry, that looks fine. I have attached both exception details in attachments.

Please guide me. Thanks in advance.

Regards,

Sweety.
