Restart dashing not working

[nikolax5]

Hi im try to install dashing for icinga2.

I had a few problems which I was able to fix but not one.
When I run ./restart-dashing I get the message.

"./restart-dashing/usr/share/dashing-icinga2/binpaths/ruby/3.2.0/gems/thin-1.6.4/lib/thin/server.rb:107:inblock in initialize': uninitialized constant Thin::Server::Fixnum (NameError)"

"when Fixnum, /^\d+$/ then port = arg.to_i"
