Rails method global params kind_in error when upgraded - ruby-on-rails

Question

I've recently done an rails and ruby upgrade, we don't have strong params in the app (I know it's legacy).
So the way it's done in the app we have the following
def all_params_permitted(this_params = nil)
this_params = params if this_params == nil
this_params.permit!
this_params.each do |i, v|
if v.kind_in?([Hash, ActionController::Parameters])
all_params_permitted(v)
end
end
end
Which loops through all params and just accepts everything, all_params_permitted is called throughout the app I would love to add strong params but that's a no-go for now.
The issue in the above method is kind_in? the upgrade I did for this app was rails 5.0.3 to rails 6.1+ and went from ruby 2.2.6 to ruby 3.0.1 so I'm not sure why kind_in? has stopped working. This is an old app (built-in rails 2) so not sure if this has been deprecated.
Any help here would be great.
Edit
I have tried kind_of? but no dice.

This is asking for trouble. It is strongly advised to try upgrading one minor version at a time (e.g. rails 5.0 --> 5.1 --> 5.2 --> 6.0 --> 6.1), otherwise you're very likely to break things with little information on why it's stopped working/how to fix it.
Likewise for ruby versions... At an absolute minimum I'd postpone the final upgrade to ruby v3 until your application works fine under ruby 2.7.
I'm not sure why kind_in? has stopped working
Nor am I, because that's a custom method. You haven't show us how it's defined, and nor have you shown us the error message, so it's impossible for me to say with confidence what's gone wrong.
My guess is that it's implemented something like this:
class Object
def kind_in?(classes)
classes.any? { |c| self.kind_of?(c) }
end
end
i.e. it's a little wrapper around the built-in kind_of? method.
And with that said, I still have no idea why this would have "stopped working" due to a ruby and/or rails upgrade.

Answer 2

Not sure about kind_in?, also didn't find any reference to that method, also as you have not posted the error so not sure about your issue. is_a?, kind_of?, instance_of? are few methods that check the object class but they check only a single class. Looking at your code one option for your condition could be:
if [Hash, ActionController::Parameters].include?(v.class)
which will check if it belongs to one of these classes.
