Jitsi videobridge not rendering when execute from source

Hi all I did a quick install and was able to get the conferencing without any issues. But when I try to run jicofo and jvb from source its running but there is no video or audio in the rendering page its blank.
However I find this error in the console of browser

I’m using the following command for running jvb and jicofo.

jvb : sudo ./jvb.sh --host=localhost --domain = jitsi . example . com --port=5347 --secret=Pif#Cl3P --apis=rest,xmpp.

jicofo : sudo ./jicofo.sh --host=localhost domain=jitsi . example . com --secret=324A7PBA --user_domain=auth . jitsi . example . com --user_name=focus --user_password=28RYB5uU

I’m actually following what was mentioned here in this link as I wanted to play with the source code.
