Looks like some unrelated tests are failing that don't fail on my machine (the best excuse always haha). I ran the suit on 3.3 and then later on on 3.1 on my local machine.

When I try it on 3.0 I can't go through bundle install:

bundle install
Fetching gem metadata from http://rubygems.org/.......
Fetching https://github.com/ruby-grape/grape-swagger-entity
activesupport-8.0.0 requires ruby version >= 3.2.0, which is incompatible with the current version, ruby 3.0.6p216

3.0 is anyways EOL according to Ruby Maintenance. Maybe it makes sense to drop the support unless you've done it already.

thanks @gregg-platogo … will merge it, and having an eye on the specs
