TypeError: String can't be coerced into Fixnum

When I use offset in my request with a big data, I have this error:

TypeError: String can't be coerced into Fixnum

Look this trace:

kaminari (0.16.3) lib/kaminari/models/page_scope_methods.rb:23:in `-'
kaminari (0.16.3) lib/kaminari/models/page_scope_methods.rb:23:in `total_pages'
grape-kaminari (0.1.9) lib/grape/kaminari.rb:14:in `block in paginate'
grape-kaminari (0.1.9) lib/grape/kaminari.rb:12:in `tap'
grape-kaminari (0.1.9) lib/grape/kaminari.rb:12:in `paginate'
app/api/development/publication/categories_api.rb:37:in `block (4 levels) in <class:CategoriesAPI>'

I think that can fix:

collection.page(params[:page].to_i).per(params[:per_page].to_i).padding(params[:offset].to_i).tap do |data|
