Could you please help me with the error?
[23:33:56.323] ERROR: Tmux[Script Filter] Code 1: /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- alfred (LoadError)

I'm not a ruby guy. Errors tells that cannot find the 'alfred' library but apparently it's part of Alfred package and it shouldn't be a problem.
Thanks in advance.
