Exact steps for others to reproduce the error

open blender and use default cube

add new material to cube

add a standard image configuration using the addon "node wrangler" (ctrl + t)

select an image for your texture node

change the mapping node from "point" to "texture" mode

try to export the cube

error pops up

I can get the error to pop up for Vector and Normal [translation/location entries are dynamically removed from the node then].
Texture mode has the entry though... I guess you are talking about that?

Anyways, we should check for that...

Scratch that, it is always erroring since blender/blender@baaa89a0bc, lets see how to get stuff from python then...

There is still the problem of missing min/max which needs a dev decission.
Will put on High meanwhile...
