When I Open the Template Editor I Receive an Attempt to De-Reference a Null Object Error

This error can occur for multiple reasons.

1

The template’s Related To Type object is missing as a picklist option

The template’s Related To Type object does not exist as a Related To Type picklist option in this org (this usually occurs when templates are imported from other orgs). Add the Related To Type object as a Related To Type picklist option.

2

Incorrectly configured lookup field on the S-Doc Relationship object

There is an incorrectly configured lookup field to the Related To Type object on the S-Doc Relationship object. Ensure that you have correctly configured a Lookup field to the template’s Related To Type object on the S-Doc relationship object.
