Steps to Reproduce



1. Log into Interaction portal.
2. Create an Interaction.

While interaction is being launched an error is observed in logs.


Root Cause




The error message in the logs is because issue in the activity CAVerticalLogTaskCompleted step 4.

The error is thrown because Step 4 is skipped if the When condition is True and throws the null step page on Step 5.

The reported issue is addressed in CPM 7.1 Release 2 ML 1. Currently developer is on CPM 7.1 Release 2.

So requested them to upgrade to ML 1 or ML 2(recommended - as it contains some extra bug fixes).

Resolution



Developer is requested to update to CPM 7.12.1.
