Testing against zeek 7.1.0-dev.552
The package doesn't install due to the baseline failing. The new version adds a 'proto' field to c$id as seen below:
[orig_h=192.168.2.186, orig_p=53798/tcp, resp_h=192.168.2.21, resp_p=1234/tcp, proto=6], 1.0 min 25.0 secs 225.0 msecs 655.078888 usecs
To support both newer and older versions of zeek I'd probably suggest being more explicit about what the tests.event script prints out and regenerating the baseline.
