EAM send tags task is failing with an error trying to send some standard tag UDTs we use from central development server to a specific production server (same UDTs successfully sent to other production servers):

> Tag JSON import operation failed [Standard]_types_/: Error\_Exception("Cannot invoke "String.toUpperCase()" because "value" is null")

Any idea what could cause this?

Ignition 8.1.41

Update: Editing the send tags task that was failing, going through all the edit steps to finish and then rerunning the task was successful. I didn't change anything, but it seems something must have been corrupted in the task config that was corrected by going through all the edit steps.
