Having issue with `undef :to_s` in my project

[naftasantos]

Getting the following error message for this line:

lib/drb/drb.rb:1119:in `<class:DRbObject>': undefined method `to_s' for class `DRb::DRbObject' (NameError)

I suggest doing the same that is done in the line below, and have:

    undef :to_s if respond_to?(:to_s)
    undef :to_a if respond_to?(:to_a)
