Can't upload files with CKEditor5 file upload

I'm on D10.1

I had the same problem, and I figured out it was connected to activating the Blazy filter in the text editor settings. So upload impossible with the Blazy filter activated in the text editor settings, while upload possible if desactivating the Blazy filter in the text editor settings.

Maybe it is rather a Blazy issue?

Symfony\Component\HttpKernel\Exception\HttpException: Temporary file could not be moved to file location in Drupal\ckeditor5\Controller\CKEditor5ImageController->upload() (line 188 of /home/my-domain/public_html/drupal/web/core/modules/ckeditor5/src/Controller/CKEditor5ImageController.php).

I'm also facing this issue in drupal 10.1.3 with ckeditor 5. This patch works fine, so created a patch so it can be applied.

Thanks @ramprassad! The #5 patch is working for me!

@ramprassad! The #5 patch is working for me! thanks!!

Had to port the patch to work with 10.2.0.
Haven't fully tested yet, but apparently fixes the problem.

I believe a new issue must be raised in core, otherwise this patch will not be committed.

Just raised an issue in core referencing this one
https://www.drupal.org/project/drupal/issues/3410827 🐛 Can't upload files Active

In my case - D10.2.2 - I did not succeed. Hopefully this log can help ...

@larruda, I've tested this patch- 3328277-ckeditor5-upload-image-2.patch on Drupal version- 9.5, I was able to reproduce this issue but while applying the patch I was getting an error & The patch didn't get applied successfully for me. (Error attached)

Hello,
On Drupal 9.5.11,
I was looking for a patch to solve the CKEDITOR5 image upload.
I've applied the first patch, https://www.drupal.org/files/issues/2023-09-20/3328277-ckeditor5-upload-image.patch → ,

• with my user profile, administration language, on a choosen language FRENCH: the patch won't work.
• with my user profile, administration language, on a choosen language NO PREFERENCE: it is working, as it is without this patch.

So this patch may fix a bug but not the concerned one (CKEDITOR5 Images upload).
Sorry to fix this conversation but I think it is important to add this detail.

I wonder whether this issue will also solve the scenario when copy-and-pasting multiple images into the editor. This results in only 1 image being saved, while the other images encounter the error:

Symfony\Component\HttpKernel\Exception\HttpException: File "public://inline-images/image.png" is already locked for writing. in Drupal\ckeditor5\Controller\CKEditor5ImageController->upload() (line 167 of /var/www/html/web/core/modules/ckeditor5/src/Controller/CKEditor5ImageController.php).

Not been able to check the patch, but maybe this is of interest.
