You're welcome, we're all here to learn.

That is helpful. If the form was filled at some point and then became empty, that almost certainly means that the page refreshed. One way for a page to refresh is to click the Register button at the top of the page. This is most likely what's happening here.

One way to confirm this would be to place debug() before press():

        ->debug()		
        ->press('@register-button')
        ->assertPathIs('/idea');

I expect that the form would be filled in at this point. Then I would try to click on the Register button inside the debug view to make sure that the form is being submitted.

If clicking on the Register button signs you up then there is a problem with ->press(). If it fails, then there is some other problem.

Another possible problem might be related to the RefreshDatabase. This needs to be enabled in the tests/Pest.php for the flow to work - around 06:00 in the video.

Without it database will not clear up between tests. Your first-ever attempt at registration would succeed, but every next run will fail because registration requires a unique email address, and that email already exists in the database (because the database didn't reset/refresh).
