The following theme is missing from the file system: jquery_ui_draggable

Admin theme : Claro

Hi aiphes, I have the same problem, after this warning do you have other like:

Deprecated function: dirname(): Passing null to parameter #1 ($path) of type string is deprecated en Drupal\Core\Extension\ExtensionPathResolver->getPath() (línea 85 de /var/www/html/mysite/web/core/lib/Drupal/Core/Extension/ExtensionPathResolver.php)

Hi,
I have both warnings.
Drupal 9.5.1
Focal Point 2.0.0-alpha2

Hi
@jmohino I've not noticed this, but I get some 500 errors in addition when authentified. But not related I think.

Me too.

I think it may be related to this issue Deprecated function: dirname(): Passing null to parameter #1 ($path) of type string is deprecated 🐛 Deprecated function: dirname(): Passing null to parameter #1 ($path) of type string is deprecated Postponed: needs info

Maybe, but no fix for the moment as I can read.

Yes, This means that lines 58 and 85 of the ExtensionPathResolver.php file would have to be changed to make the php notices disappear:

58

- return $this->extensionLists[$type]->getPathname($name);
+ return $this->extensionLists[$type]->getPathname($name ?? '');

85

- return dirname($this->getPathname($type, $name));
+ return dirname($this->getPathname($type, $name) ?? '');

So, we need to wait for an update of the core ? I just start to update to 9.5.3 my websites and the error is still here:
User warning: The following theme is missing from the file system: jquery_ui_draggable in Drupal\Core\Extension\ExtensionPathResolver->getPathname() (line 63 of core/lib/Drupal/Core/Extension/ExtensionPathResolver.php).

Today I noticed that the jquery_ui_draggable library had been installed as a dependency when updating focal_point, but it had not been enabled,

I realized when I entered extend and saw that it was not active. Maybe that's where the problems came from, my fault!!

@jmohino So what do we need to do ?

Go into your site /admin/modules and check that "jQuery UI Draggable" is enabled, if not, enable it. You can also do it with drush from the CLI with "vendor/bin/drush pm:enable jquery_ui_draggable".

If it was already activated, the only way to remove the notices is by changing the 2 lines of comment #9, for now.

OK, I enabled the module:

  jQuery UI   jQuery UI Draggable (jquery_ui_draggable)   Disabled   8.x-1.5
 ----------- ------------------------------------------- ---------- ---------
$ drush @sited9pf en -y jquery_ui_draggable
>  [success] Successfully enabled: jquery_ui_draggable
$ drush @sited9pf pml --filter=drag
 ----------- ------------------------------------------- ---------- ---------
  Package     Name                                        Status     Version
 ----------- ------------------------------------------- ---------- ---------
  jQuery UI   jQuery UI Draggable (jquery_ui_draggable)   Enabled    8.x-1.5

Will see if warning disappear. Finger cross. ;)

Hi, would it be possible to make this as a patch, the 2 lines from https://www.drupal.org/project/jquery_ui_draggable/issues/3337831#commen... 💬 The following theme is missing from the file system: jquery_ui_draggable Active ?
After updating to Drupal 10.3.0 I got the same error.
Thanks and greetings,

Hello,

 }

It solved for me the issue with the dirname() warning message

Hi, great you made the patch, could you attach it, so I can link to it within my composer.json file?
thanks in advance!
greetings,

The hint in #11 helped me, thx. Since this is clearly the cause of the originally described error message, we should close this.
