TypeError: Cannot read property 'length' of null (7.26.4)

See original GitHub issue

@testing-library/dom version: 7.26.4
Testing Framework and version: jest: 26.6.2
DOM Environment: jsdom: 8.5.0

Relevant code or config:

  test(`should select rule type from selector`, async () => {
    renderCampaignShowRoot({
      store: rootStore,
      activeRoute,
    })

    const createRuleButton = await screen.findByTestId(
      'ac-cr-loyalty-create-new-rule',
    )

    userEvent.click(createRuleButton)
    expect(
      await screen.findByTestId('ac-cr-loyalty-create-rule-modal'),
    ).toBeInTheDocument()

    const select = screen.getByLabelText('Action type')

    await selectEvent.select(select, 'Purchase points')

    expect(await screen.findByText('Purchase points')).toBeInTheDocument()
  })

What happened:

    TypeError: Cannot read property 'length' of null

      314 |           ).toBeInTheDocument()
      315 |
    > 316 |           const select = screen.getByLabelText('Action type')
          |                                 ^

      318 |           await selectEvent.select(select, 'Purchase points')

Problem description:

After update @testing-library/dom: 7.26.3 -> 7.26.4 (https://github.com/testing-library/dom-testing-library/pull/790), tests started to fall

These changes affected specs which use these helpers:

findByLabelText
getByLabelText

other specs works fine

New versions are released automatically. Unfortunately TravisCI recently made changes to their OSS plan which severely limits how frequently those runs happen. I’m investigating moving to GitHub actions for this. But you’ll get a new version soon (most likely in the next few hours). Thanks for your patience.
