Imagick not working with GAE runtime php82 or php83

[mrceolla]

We have been using Imagick with Google App Engine with runtime php81 for some time. I changed the runtime in app.yaml php83 and received the following error when testing Imagick:

Uncaught ImagickException: no decode delegate for this image format `SVG' @ error/blob.c/BlobToImage/363 in /workspace/...

I tried runtime php82 and received the same error. Why is this?

I understand there may not yet be an official Imagick release for PHP 8.3, but I think there is for 8.2. Yet php82 doesn't work either. Did I do something wrong?

I am unsure of the versions used in Google App Engine. imagick.so is an extension available in that environment by default so I did not need to install anything.

Image Magick sort of works. I can read PNG height and width with it when using runtime php82, but it cannot ingest SVG code/tags as it used to like when it was using runtime php81. Since I cannot install anything manually in Google App Engine, I am unsure how to fix or troubleshoot this. Any help is greatly appreciated.

Thanks!
