Invalid get index 'current animation'(on base: 'null instance')

Question

I don't know why this error appears:
Invalid get index 'current animation' (on base: 'null instance')

any ideas?
Thank you

seems that you wrote the wrong address to your node

if $anim.currentanimation != newanim:

did you reoganiced your Node-tree maybe?

I'll check, although I think the script code was well written.
Maybe I changed some place folder ...

Thank you.
