TypeError: Cannot read property 'run' of undefined at Context.eval

Hi Im following the documentation and I want a test that runs wcag2a and 2aa issue only but im getting a read property error im not sure why.

`// Define at the top of the spec file or just import it
function terminalLog(violations) {
    cy.task(
      'log',
      `${violations.length} accessibility violation${
        violations.length === 1 ? '' : 's'
      } ${violations.length === 1 ? 'was' : 'were'} detected`
    )
    // pluck specific keys to keep the table readable
    const violationData = violations.map(
      ({ id, impact, description, nodes }) => ({
        id,
        impact,
        description,
        nodes: nodes.length
      })
    )
  
    cy.task('table', violationData)
  }


describe('Womens T20 Cricket Test',() => {
    it('Has no detectable a11y violations on load (with custom parameters)', () => {
        cy.visit('https://www.skysports.com');
        cy.iframe('#sp_message_iframe_758392').find('.sp_message-accept-button').should('be.visible').click()
        cy.checkA11y(null, null, terminalLog, {
          runOnly: {
            type: 'tag',
            values: ['wcag2a', 'wcag2aa', 'wcag2aaa']
          }
        })
      })
    });`

Start with the documented Cypress spec usage around cy.checkA11y, cy.iframe, and the terminalLog callback, then reproduce the shown test against the reported error. Check the Cypress command setup and the exact point where the undefined value is accessed; done means identifying the cause of the TypeError and confirming the accessibility test runs with the requested tags.
