Question
Agent is not getting started and throwing exception
I have a requirement to create case using agent activity.
I created a advanced agent that call an activity.
In that activity on first step i am setting pyTransactionID property, on second step i used createWorkPage method and on third step i used AddWork method. Then i unit tested this activity and case created successfully.
Then i started the agent from SMA but it is not getting started and getting following error in error Info column:
| Exception at 20180708T131616.428 GMT: com.pega.pegarules.pub.clipboard.InvalidReferenceException: The reference <code block> is not valid.

Please help to resolve this.
Thanks in in advance.
Hi Harendra,
Could you please share the snapshot of your activity.
Yes, The problem is coming from Step 1 of CreateCases activity. Maybe a missing parameter from the very beginning?
Accepted Solution
Hi Harindra,
As rightly mentioned by everyone above, the exception is due to null step page during agent activity execution. Apparently, in the activity step-1 property-set is being done. Internally, before setting the property value, first, it checks whether the step page is set or not. If null, throws above exception. If not null, the property value will be set.
For advanced agents, the page is passed as null. So it is up to the user to have pages created in the activity. However, in case of the standard agent, the context of the operator's access group who created the queue item will be considered.
Hi Harindra,
From the error it tells that step page is null, can you please share the screen shot of activity steps and also if the activity is not checked-in it won't be picking up the changes you have made.
