Dependency issue when trying to upgrade to Rails 5.2

[ErCollao]

Hi! I'm trying to upgrade an app to rails 5.2, and I'm getting an error because the version of sass-rails is limited to 3.5.

I get the following error while executing bundle upgrade:

Bundler could not find compatible versions for gem "sass":
  In Gemfile:
    foundation-rails was resolved to 6.4.3.0, which depends on
      sass (< 3.5, >= 3.3.0)

    sass-rails was resolved to 5.0.7, which depends on
      sass (~> 3.1)
