Save a copy of InDesign file need syntax

I have a core aspect of my script in good shape, and that has no effect on what else I need it to do.
I need to have InDesign save a copy of the file and I can’t get anywhere on it. I would love to have specific examples of the syntax in application dictionaries!

tell application "Finder"
set ThisPlace to (choose folder with prompt "Where do you want to save your bingo cards?")
set BatchRound to "1"
end tell

tell application "Adobe InDesign 2025"
set TheName to the name of document 1
	my CullName(TheName) --this gets rid of the " Template.indd" part of the file name
	set ThisDoc to result

save a copy of document 1 to (ThisPlace as string) & (ThisDoc as string) & "_" & (BatchRound as string) & ".indd"

end tell

on CullName(TheName)
	set thisName to (characters 1 through ((offset of " Template.indd" in TheName) - 1) of TheName) as string
	return thisName
end CullName

I know it isn’t working, because I get the error saying: Adobe InDesign 2025 got an error: Cannot save a copy of “Bingo Card Template.InDesign”.

Error 3596

Thanks for any help!

NVM, I figured it out myself.
Adobe InDesign looks for a complete alias path after the “to”, so it cannot be constructed following the “to”, it must be constructed beforehand, then it is a simple

save a copy document 1 to alias ThisDoc

The alias must be a full path with the name of the file included.

I recommend to replace the alias thing with the POSIX path of the file. Starting from InDesign 2025, InDesign officially doesn’t support HFS paths anymore (only POSIX ones). HFS paths still do work for saving files (and maybe in a couple of other operations), but it can stop at any time.
