v2.26.0 regression: undefined method 'sym_type?' for nil:NilClass

[jtannas]

On the newly release v2.26.0 version, rubocop-rspec encounters an error whenever inspecting the command run_test! in my code

        context 'when the user does not agree to the terms of use' do
          let(:body) { valid_body.merge(tosAcceptedAt: false) }

          run_test!
        end

Environment information: 1.59.0 (using Parser 3.2.2.4, rubocop-ast 1.30.0, running on ruby 3.1.2) [x86_64-linux]

@jtannas I cannot reproduce the issue from the 5-line snippet you shared.

Would you try reducing your spec/requests/api/v1/users/url_spec.rb to the smallest possible where the error still occurs?

[Tabby]

I'm seeing the same issue and it's only affecting specs that make use of RSwag, which is where run_test! comes from

FWIW, we also have the following block in .rubocop.yml to ensure specs that use RSwag are not incorrectly parsed as lacking examples:

RSpec:
  Language:
    ExampleGroups:
      Regular:
        - path
        - post
        - put
        - get
        - delete
        - response
    Includes:
      Examples:
        - run_test!

Thank you for reporting this bug. It should be fixed by v2.26.1.
