GIMP 2.99 - plugin map-object script-fu what to fill in for unused parameters?

[nelo]

I want to use map-object to map to a cylinder.
So I do not need these options:
front-side ; box-front-drawable
back-side ; box-back-drawable
ebene-vs ; box-top-drawable
ebene-vs ; box-bottom-drawable
ebene-vs ; box-left-drawable
ebene-vs ; box-right-drawable

In the procedure browser it says we can set it to NULL if not needed.
If I put 0 there I get errors:

Error: Invalid ID of GIMP item (0 0 0 0 0 0 -1 -1 -1 2 3 0,35.0 0,05.0) 

So what’s the correct way to handle these?

[CmykStudent]

From the example here, try using -1 instead: plug-ins/script-fu/scripts/spinning-globe.scm · master · GNOME / GIMP · GitLab

[jboerema (Jacob Boerema)]

In general, Python uses None for NULL values. So that is another option to try.

Strike that, for some reason I missed that it was about script-fu.

Thank you.
That does indeed work.
(Should be corrected in the procedure browser.)
