Error: Call to a member function getOption() on null

My suggestion is to check an interface similar to
https://git.drupalcode.org/project/drupal/-/blob/11.x/core/lib/Drupal/Co...

Updated #11 patch,
* checked if url implements Drupal\Core\Url,
* added a simple test,

This patch work for me #15 -> menu_link_destination-fatal_error_when-no_url-3251757-15.patch
But @alorenc
i can see some error in the site after applying patch

Keeping in in review for the error message

I dug into the problem and I don't think there is any issue with this module. The docblock of the Link render element declares that #url must be a \Drupal\Core\Url object - so Menu Link Destination can assume that the value at this key is a Url object.

1. Based on #10, the reported issue is caused by Admin Toolbar Extra Tools (link renderable array without #url).
2. @alorenc had another case where the error was slightly different (calling getOption() on bool) - and that is casued by a link renderable having #url key set to FALSE. This link is created by Webform; see 🐛 Webform might create invalid link renderable arrays on submission list. Needs review

I propose to close this issue, referring the corresponding bug of the contrib modules. Maybe the module could check if the link renderable array it is processing is a valid and log an error if it isn't... But wouldn't that be overkill? (Imho it wold be.)

Adding the related Webform issue.

correct, the link element describes URL property as \Drupal\Core\Url but at the same time it checks if it is URL
https://git.drupalcode.org/project/drupal/-/blob/11.x/core/lib/Drupal/Co...

I do not see any reason why we can not do the same, it will be simply more resistant to mistakes.

Thank you all
