NoMethodError: undefined method 'path' for class RSpec::ExampleGroups:: - Problem using rswag (swagger_helper)

I have the following code to generate Swagger docs:

require 'swagger_helper'

RSpec.describe 'Transactions API', swagger_doc: 'v1/swagger.yaml' do
  path '/transactions' do
    get 'List transactions' do
      tags 'Transactions'
      produces 'application/json'
      parameter name: :user_id, in: :query, type: :integer, description: 'User ID (optional)'

      response '200', 'transactions listed' do
        schema type: :array, items: {
          type: :object,
          properties: {
            transaction_id: { type: :integer },
            user_id: { type: :integer },
            from_currency: { type: :string },
            to_currency: { type: :string }
          }
        }
        run_test!
      end
    end
  end   
end

I am running the following code to generate the Swagger docs:

$ bundle exec rake rswag:specs:swaggerize

But I am getting the following error:

$ bundle exec rake rswag:specs:swaggerize

How to solve this problem?

After searching, I found the following solution in the rswag GitHub, described by Nikita Ignatovich: we must uncomment the config.infer_spec_type_from_file_location! line in the file spec/rails_helper.rb.

Other option is using the type: :request in addition to the `swagger_doc` option. Thus, your line must be like this:

RSpec.describe 'Your API', type: :request, swagger_doc: 'v1/swagger.yaml' do
