Using the importFile command from the Illustrator CC AS Dictionary

Here is the dictionary entry
importFile (verb)Import the file into current Ai document (from Adobe Illustrator Suite)
COMMAND SYNTAX
importFile document ¬
from file ¬
is linked boolean

Here is my script

tell application "Adobe Illustrator"
	set theDoc to current document
set itemRef to importFile theDoc ¬
		from file ¬
		"Macintosh HD:Users:chrisndeca:Downloads:helloworld.jpg" without is linked
end tell

This script running with Illustrator 25.3 gives me a Parameter Error every time it is run. I have narrowed the error down to being with the “file” parameter and not the document parameter. I have tried Posix File, I have tried posix path, I have tried an alias for the file parameter, but none of them work. What the heck am I missing?

Or is Illustrator just broken when it comes to “importFile”?
