Update Core to 10.1.8
go to image styles
edit any of the existing image styles
website will encounter error

I've experienced the same problem with a number of 10.3.2 installation. I just haven't need to edit styles before so I could only follow the discussion yet.

@eyad alanati, thanks for providing the steps to reproduce. Can you add them to the issue summary to help others who work on this issue?

I tested this on Drupal 10.1.8 using the steps in #9 and did not receive any errors. Leaving the 'steps to reproduce' tag because there seems to be something more that needs to be done to reproduce the error.

Also changing to Unassigned so that others may look at this.

Original image height or width is zero.

What is the image.settings:preview_image config set to on those sites?

I am also getting the same error on Drupal 10.2.4. But this error only comes when switching to the ImageMagick toolkit, not with GD.

image.settings:preview_image: core/modules/image/sample.png

Drupal 10.1.x is no longer supported. Changes are made on on 11.x (our main development branch) first, and are then back ported as needed according to our policies.

Can someone add steps to reproduce in the Issue Summary. I have tried the ones from #9 and did not get the problem.

Really change to 11.x

Is anyone still experiencing this one? If no follow up in 3 months could be closed out.

I'm trying to update some image styles tonight and seeing this issue. I haven't had a reason to edit any of these in a while, so not exactly sure when it was introduced, but trying to edit almost all of my image styles is leading to the following:

Uncaught PHP Exception DivisionByZeroError: "Division by zero" at /var/www/html/docroot/core/modules/image/image.admin.inc line 77 request_id="v-bcc3ba58-522d-11f0-a348-f768f1d28ced"

We're on 10.4.5. I'm trying to add Convert to Webp to a bunch of theses styles, and I'm getting this Division by Zero error on essentially every image style. Strangely, they are all editable on my Stage and Dev servers. Somehow corrupted only on Prod. Any thoughts?

I know that patch associated with this issue is for an older version. Any thoughts on why we might be seeing this error?

I am having this same issue on a relatively new and clean site, but it is along with another issue. Custom fields have no problem storing data in private://* but upon editing a built-in Image Style, or upon creating a new style, the corresponding folders are not created, and I get two messages in the Drupal log:

Failed to create style directory: private://styles/wide/private/core/modules/image

and

DivisionByZeroError: Division by zero in template_preprocess_image_style_preview() (line 77 of /.../web/core/modules/image/image.admin.inc).

The second error corresponds to an error in the php log. For the first error, there are no entries in either the php or http logs. The directory create failure is always first in the logs, but I cannot find a valid reason for why there is an error. Everything in the system setup and file permissions are fine. The last test was to toggle SELINUX and now I am out of ideas.
