Undefined constant "Drupal\node\Entity\DRUPAL_OPTIONAL"

I tested the patch and it resolved the problem. Thank you for your work!

(I can reproduce with editing the content type "basic page". After saving the form i get a WPOD.)

It was only a quick check and I could not test the whole system so I do not set the status to "Reviewed".

Thanks @jan for the feedback.

The same. I've deployed this patch to a project on production, it works well (but has some other issues similar to this one with classes not defined, whereas they are) only once, and I have no idea what triggered it.

Though this project has no cache and page_cache has been uninstalled, so the same, I can't really set this patch to "reviewed".

Let's wait for a while and we'll see.

Thanks for the patch. I reviewed and tested and can confirm it works.

Prior to the patch, I was able to reproduce the error by creating a webform and then deleting it. Upon deletion, I got the DRUPAL_OPTIONAL error and WSOD. Flushing cache was the only way to fix. After applying the patch, I can create and delete webforms without the error.

I think it's quite safe.

I've been using this fix for a while and it seems to work.

Will release soon.
