- Check the Browser Console: Press
F12(or right-click and select Inspect), navigate to the Console tab, and look for red text readingUncaught Drupal.AjaxError. [1, 2] - Inspect the Network Payload: Go to the Network tab in DevTools, trigger the error again, click on the failed request (highlighted in red, often returning a
500status), and check its Response or Preview tab for the raw PHP error. [1, 2] - Check Drupal’s Database Logs (DbLog): If you have administrative access, navigate to
/admin/reports/dblogto look for recent PHP, Apache, or Views errors recorded at the exact timestamp of the failure.
- Check the Browser Console: Press
-
- The Cause: If you are building a View or using a preview that displays thousands of rows at once, the server may run out of memory or exceed max processing variables. [1]
- The Fix: Go to your View configuration. Under Pager, change Use Pager from displaying all items to a lower, paginated limit (e.g., 10, 20, or 50 items). [1]
-
- The Cause: Enabling AJAX on a View with certain combinations of exposed filters or sorting options can cause a known core layout breakage. [1]
- The Fix: In the View settings panel under Advanced, toggle Use AJAX to No. If AJAX is strictly necessary, ensure your Drupal core is updated to its latest minor version or search for active patches in the Drupal Core Issue Queue.
-
- The Cause: Contributed modules like
Metatag Views,Views Bulk Operations, orLayout Builder Tabsfrequently trigger this AJAX crash when rendering previews. - The Fix: Temporarily disable the suspected module to isolate it. Check the module’s issue queue on Drupal.org for specific compatibility patches matching your current core version. [1, 2, 3]
- The Cause: Contributed modules like
-
- The Cause: Production sites are configured to mask explicit errors from end-users, forcing Drupal to display the generic “Oops” screen.
- The Fix: If you are developing locally, navigate to
/admin/config/development/logging. Change Error messages to display to All messages to print the exact file line numbers and plugin exceptions directly on your screen. [1]

views_field_view contributed module. [1, 2]views_ui_build_form_url() was completely deprecated and removed. Core replaced it with an object-oriented method: buildFormUrl() via the ViewsFormHelperTrait. [1, 2]views_field_view module still tries to call that deleted core function on line 120 of View.php, the backend crashes with a 500 Fatal Error every time you click to configure your global view field (view_2) inside the people_details view layout.

- Open your project’s root
composer.jsonfile. - Ensure you have the
cweagans/composer-patchesplugin installed. - Add the patch to your
extrasection:json"extra": { "composer-patches": { "drupal/views_field_view": { "Fix Drupal 11.4 views_ui_build_form_url removal": "https://drupal.org" } } }Use code with caution.(Note: If a consolidated
.patchfile isn’t directly attached to that issue yet, pull the latest.diffor update to the dev branch8.x-1.x-devvia Composer). - Run
composer update drupal/views_field_viewto download and apply the code fix. [1, 2]
- Open your project’s root
-
- Open the file on your server:
/var/www/archbio.miami.edu/html/drupal-11/web/modules/contrib/views_field_view/src/Plugin/views/field/View.php - At the top of the file, make sure the class imports the required Core trait by adding this line alongside the other
usestatements:phpuse Drupal\views\ViewsFormHelperTrait;Use code with caution. - Inside the class structure itself (usually right after
class View extends FieldPluginBase {), incorporate the trait:phpuse ViewsFormHelperTrait;Use code with caution. - Find line 120 where
views_ui_build_form_url($form_state)is called, and swap it to use the new object method instead:php// Change this: 'url' => views_ui_build_form_url($form_state), // To this: 'url' => $this->buildFormUrl($form_state),Use code with caution. - Clear your Drupal cache via the performance interface or by running
drush crvia terminal for the fix to take effect. []
- Open the file on your server:
View.php, or if you need the exact syntax to implement the Composer patches configuration for your specific environment!
R:
views_field_view module’s codebase on your server didn’t perfectly match the line numbers or structure expected by that specific community patch file, causing a git conflict during the patch attempt.composer update on this module until an official new release (like a 2.0.1 or 8.x-1.2) is published by the maintainers. If you update it via Composer right now, your manual changes will be overwritten, and the 500 crash will return.
