{Error on Activating SLA: Workflow containing error.Please correct the workflow and try again}

All, 

Recently, I got this error while trying to activate the SLA.  I was checking and double checking the SLA actions. Everything looks normal. I was out of clue on this how to fix this issue?

As i mentioned in previous post Error on updating SLA triggering field……….., started looking out for the error code description using this Error code link.
