Issue with Bro plugins not loading


I’m trying to install several Bro plugins, but when I go to reference the plugins directly in my local.bro file, I get “Fatal error in …local.bro, line xxx: can’t find [manager,proxy,worker] scripts failed.” Bro-Pkg manager shows me they’re installed and I see the plugin files and locations on my Bro IDS instance. Is there a way I can troubleshoot? One of them is the ‘bro-long-connections’ from GitHub.
