Error when added to 404 pages

Hi @adrianopulz,
I have fixed this issue and also created MR for this issue . please replace The 'internal:/' URL is a reference to the internal path '/', which typically represents the homepage of your Drupal site. In other words, it's setting the fallback URL to the site's homepage.

Thank you!

Thanks for your fork @shreya_th!

The problem is for URLs created from the Request, URLs from the route will not be a problem. You added try/catch to the URL created from the route when the display['display_options']['path'] is set. We need the fallback only in the createFromRequest() call.

I've added a patch with the change example. I don't think we need to change the block of code using the UrlFromRoute.

What about other system paths?

That snippet of code has been removed in another fix. Can you confirm this is still an issue.

Hate to be reopening this issue, but the issue is still there using the latest 7.x release.

We worked around the issue for now by modifying the code to be as follows:

use Symfony\Component\Routing\Exception\ResourceNotFoundException;

protected function getExposedFormActionUrl(FormStateInterface $form_state): Url {
    $request = \Drupal::request();
    try {
      $url = Url::createFromRequest(clone $request);
      $url->setAbsolute();
      return $url;
    }
    catch (ResourceNotFoundException $e) {
      return Url::fromRoute('<front>')->setAbsolute();
    }
  }

A patch will follow, I expect this code needs some better attention.

Created MR!86, here's the respective patch.

MR should be against 7.0.x but let’s add test coverage also

Could the steps be flushed out.

I added a view block that's used better exposed filters to 404 page and not getting any error.

On 10.3

I've got the same issue. I've defined a global "search" exposed form in block, which is added to the header of the website. Then on all 404 pages it shows the same error.

I've tried the patch in #12 and it went nicely, even if I'm still using the 6.x version. The patch fixed the issue, at least there is now no more errors.

Still needs step to reproduce fully or going to close out

We started seeing this issue recently with better_exposed_filters 6.0.6 after upgrading core

As with #15, we have an exposed search form in the header block which shows on all pages.

From our tests so far, the patch in #12 seems to fix the issue, but we will test further.

I've updated the steps to reproduce.

Let’s open an MR for 7.0.x and add a simple test case

Having tested further, it seems like the patch fixes the problem for logged-in users, but not anonymous.

With this patch included, we observed a strange issue where BEF checkboxes showed 0 instead of the expected markup.

In our case, this seems to relate to facets, as mentioned in #20

The mention of better_exposed_filters in the stack trace isn't the root of the problem for us.

When a facets block appears on a 404 page, it causes problems with URL generation.

I think that the appropriate fix relates to one of these issues:

#3291943: When rendering facets on non search page, it throws error instead of 404 on 404 pages →
🐛 ResourceNotFoundException with ajax facets when site running in subfolder Needs review

In \Drupal\facets\Plugin\Block\FacetBlock::build, if we add a condition to stop the block rendering on 404 pages, the problem goes away.

@idflood, @alex.bucach, @adrianopulaz, @johan den hollander - do the stack traces you see also mention facets?

Even with our patch to facets in place, we encountered this error again, although in a slightly odd scenario that came up via a penetration test, with some special characters in the URL.

Our search results page is at /search-content - the security scanner managed to trigger this exception at /search-content%22%3bexpr%20268409241%20-%2028291%3b%22?search= (and some other similar URLs).

When we apply the patch in #12, it addresses the issue.

The error mentioned in #21 seems to have been happening because we were using an incorrect patch for 🐛 Links with "Show hierarchy in dropdown" disabled gives "Deprecated function: range(): Passing null to parameter #1" Active
