That file needs to be executable. I don’t know how you copied or installed that jupyter application, but the file permissions didn’t seem to be preserved. You just need to chmod +x on the source file (/var/www/ood/apps/sys/jupyterlab/template/script.sh.erb?).
So however you’re saving this app (I know git saves mode bits) you just need to save the executable file. Just to be sure any template/*.sh.erb files should be executable.
