For the Escalation within the activity to occur after set amount of days (3 days as an example) has been specified within the workflow. The issue occurs here after the 3 days have passed and a direct Database alteration has been done to update the back-end table to be set for 3 days.

(It is recommended to not perform any database alterations as this will impact the process!)

The following error is seen: 

Value cannot be null. Parameter name: type

Before You Begin

Make sure you have the escalation settings set to the following:
Set Template = Escalate On Escalate On Settings = This can be either Specific Or Dynamic Working Hours = (Your Own Personal settings are applicable here) Action Template= What type of escalation you want it to be.

How-to Steps

This should not be tampered with in the DB, direct modifications are not recommended as this is when the error may occur here. If you let the workflow run naturally on its own you should not receive the error.

Do not modify any database definition or database content unless specifically instructed to do so by K2. No changes to the K2 Database definition or content are supported unless specifically instructed by K2.
