Empty Expiration Field Causes WSOD

Good catch, thanks for reporting. And yes, declaring this form field as required is the right way to go. Still, I'm surprised that the form validation doesn't catch an empty field since there is the constraint '#min' => 1,.

I've changed the version to 3.0.x since we always work from the latest release backwards with bug fixes and new features. Do you want to provide an MR for this? If not, I can do that later, too.

Hello,
I've created MR.
Please check and review.

Thank you!

Thanks, that's exactly it. Committed to 3.0.x and backported to 2.1.x and 2.0.x

Thank you! That's fast work and I appreciate the fix. I guess I should learn about creating an MR when I find these issues.
