Couldn’t get image transform URL: Failed to generate transform

[bmilagre]

I have the Serverless Imager according to the tutorial Setting Up Your Own Image Transform Service and Setting Up AWS S3 Buckets + CloudFront CDN for your Assets. Also the volume is linked to S3 (upload & download works).

Unfortunately, however, every time I try to transform an image I get the following error:

2023-01-14 08:43:58 [queue.WARNING] [craft\elements\Asset::_url] Couldn’t get image transform URL: Failed to generate transform with id of 42696. {"memory":14449840} 
2023-01-14 08:43:58 [queue.ERROR] [craft\errors\ImageTransformException] craft\errors\ImageTransformException: Failed to generate transform with id of 42696. in /var/www/html/vendor/craftcms/cms/src/imagetransforms/ImageTransformer.php:476

Maybe also worth mentioning that every time I open the entry, a job with Generate transformed images is executed?

Would be grateful for some help
