cameradar: Can't access camera with custom route

Issue from @johny77g ( https://github.com/EtixLabs/cameradar/commit/cad7d24ccf068d7d45dcf9db746140ec716ee219#commitcomment-25169225 )

Hi, I exposed my camera for a simple test with very simple setup username: admin, password: admin. Updated credentials.json and routes as below. With option -l the generated connections were following:

DESCRIBE rtsp://:@x.x.x.x:x/tcp/av0_0 RTSP/1.0 (no usr and no login)
DESCRIBE rtsp://:@x.x.x.x:x/udp/av0_0 RTSP/1.0 (no usr and no login)
DESCRIBE rtsp://admin:admin@x.x.x.x:/ RTSP/1.0 (no command from routes)

BUT the right configuration was never generated. (I mean with: admin, admin, tcp/av0_0) Is it something wrong with my trial or some issue with attack.go file?

----------credentials.json----------------
{
"usernames": [
"admin"
],

"passwords" : [
"admin"
]
}
--------------routes--------------------
tcp/av0_0
udp/av0_0
