Exception if entity reference is not valid (got deleted)

Problem/Motivation

If the entity reference used for the link for some reason (entity was deleted) does no longer exist, field group link creates an exception:

Call to a member function toUrl() on null in Drupal\field_group_link\Plugin\field_group\FieldGroupFormatter\Link->getUrlFromField()

While it is probably bad habit to delete entities that are referenced elsewhere, this is something that can (easily) happen and should not result in WSOD imho.

Steps to reproduce

  • Use a reference field for the link
  • delete the entity that is referenced in the field
  • visit the page where the link should be shown

Proposed resolution

Check if there is a valid entity reference (like there is already a check for a valid file entity if file is used) and skip the url generation if there is no valid entity reference
