With Rails API - TypeError (can't convert ActionController::Parameters into Integer)

[belgoros]

I'm getting the below error when using with Rails 5.2.2 in API mode and active_model_serializer gem:

#adresses_controller.rb

def index
    @addresses = Address.all.paginate(page: params[:page], per_page: 25)
    json_response @addresses
end

Error stack trace:

Started GET "/api/addresses?page%5Bnumber%5D=2&page%5Bsize%5D=25" for 127.0.0.1 at 2019-02-25 10:01:39 +0100
   (1.6ms)  SELECT "schema_migrations"."version" FROM "schema_migrations" ORDER BY "schema_migrations"."version" ASC

TypeError (can't convert ActionController::Parameters into Integer):
  
app/controllers/v1/api/addresses_controller.rb:7:in `index'

json_responseis just a concern method defined in controllers/concerns/response.rb as follows:

module Response
  extend ActiveSupport::Concern

  def json_response(object, status = :ok, opts = {})
    response = {json: object, status: status}.merge(opts)
    render response
  end
end

If the first 25 records are sent with success, the response erros happen when hitting next link provided in JSON reponse:
http://localhost:3000/api/addresses?page%5Bnumber%5D=2&page%5Bsize%5D=25

When changing the URL manually from, next provided in the JSON response:
http://localhost:3000/api/addresses?page%5Bnumber%5D=2&page%5Bsize%5D=25

to:
http://localhost:3000/api/addresses?page=2&per_page=25, it works as needed.

What am I missing? Thank you.

Used versions:

Rails 5.2.2
Ruby 2.6.1
will_paginate 3.1.6

Hi, I can't tell from the provided information what exactly generated the ?page%5Bnumber%5D=2&page%5Bsize%5D=25 URL, but those query parameters are obviously wrong. The problem is in whatever generated that link. I don't think that happened inside the will_paginate library.
