Python2 ERROR when starting Octolapse

Hey,
i connected a Nikon D7000 and it works fine with gphoto2.
But when I start printing I receive "Camera Error" and the part from log is:

2020-11-03 13:14:12,063 - octolapse.script - ERROR - An error occurred while executing 'Nikon D7000 - Snapshot Camera Script'
Traceback (most recent call last):

And the strange part is the script "/home/pi/scripts/take-snapshot.sh" works fine from SSH,
but in Test Script in camera prefrences it's not work from there.
What can be the problem?
