How do you test repeaters?

Livewire::test(CreateFlexListing::class)
  ->fillForm([
      'occupationId' => Occupation::factory()->create()->id,
      'description' => 'Looking for help with our Laravel app!',
      'shifts' => [
          [
              'date' => '2023-02-16',
              'to' => '17:00',
              'from' => '09:00',
          ],
      ]
  ])
  ->call('save')
  ->assertHasNoFormErrors();

Component has errors: "data.shifts.5c4b1833-1895-4afb-9689-c763674b6672.date", "data.shifts.5c4b1833-1895-4afb-9689-c763674b6672.startsAt", "data.shifts.5c4b1833-1895-4afb-9689-c763674b6672.endsAt"
