Why am I getting a Compiler Error with UpdateAfterGet() highlighted?

LegacyHow this worked in the previous version

When I simulate my model I get the following error:

Compiler Error, UpdateAfterGet()

Reason:

You have tried to Get an entity rather than a resource.

Solution:

Change the object you are getting from type Entity to type Resource, or if you have incorrectly entered the Get object, add the correct object.
