When using audiofield for file fields with jplayer or MediaElement Player selected, Drupal throws these php warnings in Drupal log and on the website:
Warning: array_merge(): Expected parameter 1 to be an array, null given in Drupal\Core\Theme\Registry->mergePreprocessFunctions() (line 671 of /app/web/core/lib/Drupal/Core/Theme/Registry.php)
Warning: array_diff(): Expected parameter 2 to be an array, null given in Drupal\Core\Theme\Registry->mergePreprocessFunctions() (line 670 of /app/web/core/lib/Drupal/Core/Theme/Registry.php)
Notice: Undefined index: preprocess functions in Drupal\Core\Theme\Registry->mergePreprocessFunctions() (line 670 of /app/web/core/lib/Drupal/Core/Theme/Registry.php)
Use audiofield ("drupal/audiofield": "1.x-dev@dev") with the bootstrap theme (Bootstrap 8.x-3.23).
It looks like that all warnings are related and the issue has somehow to do with:
/**
* Implements hook_theme_registry_alter().
*/
function audiofield_theme_registry_alter(&$theme_registry) {
/*
* By default, Drupal 8 does not include theme suggestions from inside the
* module in which they were created, so we must add them manually here.
*/
$path = drupal_get_path('module', 'audiofield');
$audioplayer_templates = drupal_find_theme_templates($theme_registry, '.html.twig', $path);
foreach ($audioplayer_templates as &$audioplayer_template) {
$audioplayer_template['type'] = 'module';
}
$theme_registry += $audioplayer_templates;
}in file audiofield.module. When I deactivate the last line, there are no warnings anymore.
The full log for the first warning is:
