Sorbet Error - The Super class UserBase of UserEmbeds does not derive from Class

I've been very interested in adopting sorbet for strict types in ruby, but while installing it on my existing codebase i've run into a wall that I dont understand

I get the following error when running sbc tc

entities/user_entities.rb:25: The super class CrewManagement::Entities::UserBase of CrewManagement::Entities::UserEmbeds does not derive from Class https://srb.help/5067
    25 |    class UserEmbeds < UserBase
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^
    entities/user_entities.rb:6: CrewManagement::Entities::UserBase defined here
     6 |    class UserBase < CrewManagement::Entities::Mongoid
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

the sorbet docs say under error 5067

A class’s superclass (the Parent in class Child < Parent) must be statically resolvable to a class, not a module.

From what I understand, the error is saying that my class is not inheriting from a class, instead its suposedly inheriting from a module, but when I look at everything, i'm pretty sure everything is a class and that sorbet might be throwing a false positive.

entities/user_entities.rb

module CrewManagement
  module Entities
    ## inherits from a different file
    class UserBase < CrewManagement::Entities::Mongoid
      expose :username
      ## ...
    end
    
    ## inherits from declaration above
    class UserEmbeds < UserBase
      expose :_embedded do |record, opt|
        embeds = {}
        ## ...
        embeds
      end
    end
  end
end

config/entities.rb

module CrewManagement
  module Entities
    ## inherits from grape-entity gem
    class Mongoid < Grape::Entity
      format_with(:mongo_id, &:to_s)
      with_options(format_with: :mongo_id) do
        expose :_id, as: :id
      end
      expose :created_at
      expose :updated_at
    end
  end
end

I think its flagging the grape-entity rubygem and not my codebase, but when i look at the rubygems source code i find that Grape::Entity is a class https://github.com/ruby-grape/grape-entity/blob/master/lib/grape_entity/entity.rb

Is the error something that I can resolve with an RBI file declaration?
