  * /usr/sbin/iptables -A INPUT -p tcp --dport 80 -m string --algo bm --string 'GET /?twclid=' -j DROP
Bad argument `/?twclid=''
Try `iptables -h' or 'iptables --help' for more information.

It maybe occurs follow code. https://github.com/Joungkyun/oops-firewall/blob/439be7f6d9d145412305632f4d2d9e4181b9f766/src/include/command.h#L403-L404

It will need to execute with eval function
