Issue with the converter, imagick error

[djpmedia]

I've setup a Docker container with php7.4 and imagick. When i run /test.php everything is oke.

Checking environment for running PDF to Pageflip5 converter and API

php.ini settings (needed):
upload_max_filesize = 128M (128M only for converter)
post_max_size = 128M (128M only for converter)
max_execution_time = 0 (0)
max_input_time = 1000 (1000)
max_input_vars = 300000 (300000 only for converter)

ImageMagick test:
imagick installed.
imagick version: ImageMagick 6.9.11-60 Q16 aarch64 2021-01-25 https://imagemagick.org
(needed version 6.7 or newer)

Database test:
OK.

When I upload a PDF, everything should be running as aspected besides that the preview thumbnails are blank. When I look to the logs, it said that de job is finished, but I have some imagick errors:

I can't figure out what the imagick errors are. Maybe some php modules/extensions are missing, or the Imagick version is wrong.

Maybe you can help?

As this PDF converter was designed to run on a single server environment, it lack a lot of error checking/reporting which causes situation like this a pain to debug... While I'm searching what could be gone wrong, I start working on error handling.

Until then, it worth looking at the php error.log file too for additional error logs.

Added error reporting for the background process. Check background.log after updating.
