Solved 500 Error on .png image files

Running latest beta on my production and dev site.  Both use php 8.2.  I just noticed that image .png files show a http 500 error when acessed.
On the individual page, the thumbnail shows the 500 error if I am logged in and if I click on the image I get the actual image file.
skatekey.net/tree/peters/individual/I001...ctoria-C-Schmidbauer

However, if I am not logged in then the thumb shows the correct image but when I clickon the thumbnail I get a 500 error.
 

This is a bit strange indeed.
Part of list of Media Objects:
skatekey.net/tree/peters/media-list?go=1...rmat=&max=20&page=16

The media object on its own:
skatekey.net/tree/peters/media/M66/Victoria-Schmidbauer

Response headers show just a "200-OK"

I'm curious what's logged in your server error log...

Hi Rob,

If you look at the HTTP headers for this "500" image, you will see a webtrees error message:

x-thumbnail-exception: Error: Unknown named parameter $quality

Looking at the code, this exception is caused when calling the intervention image library.

Since you are using the 2.2.0-dev code, my guess is that you haven't updated your vendor directory.

You'll need to run `composer install` (or more likely `composer install --no-dev`) to update these files.

Actually, I did. 

However, I use rsync to update my prod system and dev systems.   So, I tar'ed my source vendor folder and completely replaced the prod system's vendor folder and that fixed it.   I did a diff on the folders and  there were lots of undeleted files in vendor folder.
