First operand of . is NULL, so cannot access member trace_flag

I am currently working on a PeopleSoft Upgrade from 8.9 to 9.2 and we've encountered an issue where our Custom Approval Workflow Engine is not working (not routed to the approver).

Below are the steps that we've done so far:

1. Changed all the codes referencing "SAC" objects to "EOAW" since the naming convention have been changed in 9.1 or 9.2.
2. Setup the Approval Process Setup and Transaction Registry and Transaction Configuration. Navigation: Enterprise Components>Approvals>Approvals>...

As of this writing, there's an error "First operand of . is NULL, so cannot access member trace_flag" encountered when adding data on the page.

The specific code that's erroring out is &c_aweLaunchManager.appDef.trace_flag = True;
