Error on starting binary cache client

[jurraca]

On starting the trustix-nix-cache service, the LogAPIClient gets started with a URL which, according to this comment should be the base URL of the cache we're setting up. But it seems to get started with the trustix socket addr, as you can see in the first line of debug message in the log dump below (address="unix:///run/trustix-daemon.socket").
Should I set the URL somewhere? I'm not setting the socket addr as the URL anywhere so not sure how this is supposed to work. Any insight would be appreciated. (sorry if this is obvious, not great at parsing Golang)
Thanks!
