[ALERT] (58316) : config : Error(s) found in configuration file : /opt/homebrew/etc/haproxy.cfg
[ALERT] (58316) : config : Fatal errors found in configuration.
[NOTICE] (58317) : haproxy version is 3.0.3-95a607c
[ALERT] (58317) : config : parsing [/opt/homebrew/etc/haproxy.cfg:34] : 'option httpchk' : hiding headers or body at the end of the version string is unsupported.Use 'http-check send' directive instead..
The line 34 should expand into like
option httpchk
http-check connect port 3000
http-check send hdr host localhost meth GET uri /
http-check expect status 200

I hope it helps!
