Unable to locate docker environment variable in source code

Hi,

I can see in the docker-jitsi-meet repository under the branch stable-8252 and stable-8319 that there is an environment variable called JICOFO_COMPONENT_SECRET defined in the docker-compose.yml file but could not find any reference to it within the docker image definition of jicofo.

Can you point out where this environment variable is used?

That can be removed. Jicofo is no longer using a component.

is JVB_TCP_HARVESTER_DISABLED still referred to in JVB?

That is not a thing.
You can check it yourself:
