I can't seem to get logs from my Roku device when I try to capture HTTPS traffic.
I constantly receive 503 errors with "Invalid first line in request".
What could I be missing?

The script is prepared to catch a single pf rule.
So in order to add both http and https, they need to be together in the same string.
var pfrules = [ 'rdr pass on bridge100 inet proto tcp from any to any port 80 -> 127.0.0.1 port {charles_port} \n rdr pass on bridge100 inet proto tcp from any to any port 443 -> 127.0.0.1 port {charles_port}' ];
