Please show us your code, and make it as simple as possible. Like this:

--------------------------------------

#!/usr/bin/ruby -w

b = "b"

b_id = b.object_id

ys = [ "a",b,"c","d" ]

puts ys.find { |i| i.object_id == b_id } # => "b"

puts ys.find { |i| i.object_id == b } # => nil

puts ys.find { |i| i.object_id == "b" } # => nil

--------------------------------------

Notice in your version of the code that "id" must equal the object id, not
the object.
