Error when repack squashfs

[santa2021]

Hi, when i run repack script, i getting this error:
Unknown argument -sp
Output padding file not specified

Is the argument -sp specified correctly?
And if I write -p padding everything is going well, which option is more correct?

Go to point 6.2. The script may malfunction in some versions of Linux.

For which device are you trying to do this?
