Running into undefined method 'parse' for class CGI on Ruby 4.0.1

[kushagra-03]

Thanks for the great work!
Trying to integrate devise_toke_auth with a rails 8 app, ran into this undefined method 'parse' for class CGI on Ruby 4.0.1.

Another issue after I got the above to work:
no implicit conversion of Regexp into String

class Wildcat
    def self.parse_to_regex(str)
      escaped = Regexp.escape(str).gsub('\*','.*?')
      Regexp.new("^#{escaped}$", Regexp::IGNORECASE)
    end

Help would be appreciated!
