Help with Transmission docker unrar (unpack) script please?

Hi,

I am trying to run a script that works on my transmission install on a VPS but I cannot get it to work on my unRAID transmission docker,

Here is the script and it is marked as executable

#!/bin/bash

find /mnt/user/generaldata/unraidapps/transmission/downloads/ -name '*.rar' -execdir unrar e -o- {} \;

but the error I get when I try to run it is

root@UNRAIDSERVER:/mnt/user/generaldata/unraidapps/transmission/config# sh unrar.sh

find: The current directory is included in the PATH environment variable, which is insecure in combination with the -execdir action of find.  Please remove the current directory from your $PATH (that is, remove "." or leading or trailing colons)

I would really appreciate any kind of help!

Many Thanks in advance!
