Error in configure_server! when listen_port not defined.

[vpuri3]

Bonito.jl/src/server-defaults.jl

Lines 125 to 132 in ebba54d

	if isnothing(listen_url)
	if !isnothing(proxy_url)
	# if we serve to an external url, server must listen to 0.0.0.0
	listen_url = "0.0.0.0"
	else
	listen_url = SERVER_CONFIGURATION.listen_url[]
	end
	end

When listen_url is not defined, it is set to SERVER_CONFIGURATION.listen_url[] which is set to nothing. This trips the error in line 140 as follows:

julia> using Bonito
