So my team found that loading properties of fields (i.e. "isDisplay" "isVisible") loaded from records in dynamic mode throws errors on the server side for suitescripts utilizing SS 2.1. The script fails in the highlighted part in 2.1 but not 2.0. This is especially confusing because JS should never throw errors for undefined properties

isDisplay uses a getter

Its a boolean in the documentation

Its under "Property" in the NS docs and described as a "boolean"

the getter is supposed to return a boolean generated by the function call

As a property it works in 2.0. We do not use a "getter"

im explaining why you are getting a function related error

Run as a function it errors out still

you dont call it like a function

Okay so NetSuite is throwing an error because isDisplay is using a getter in its field object behind the scenes and that has a bug?

i was only explaining why you got an error that looked like it came from a function

I understand that now.
