$this->numberOfPages = $this->imagick->getNumberImages(); causes Maximum execution time of 30 seconds exceeded

[trevorpan]

Have laravel medialibrary installed. It works fine for single page files. However a four page 8.5MB (and a smaller 2.5MB of the same file) pdf throws this:

Maximum execution time of 30 seconds exceeded or 502 Bad Gateway

Single page files do not throw the error.

Tried out a ton possible issues, but the error always comes back to a method in vendor/spatie/pdf-to-image/src/Pdf.php file.

Here's the versions I'm using:
"spatie/laravel-medialibrary": "^7",
"spatie/pdf-to-image": "2.0.1",

Laravel 7
GPL Ghostscript 9.50 (2019-10-15)

php.ini
upload_max_filesize = 32M
max_file_uploads = 20
post_max_size = 128M
memory_limit = 2048M
extension="redis.so"
extension="imagick.so"

Laravel Valet 2.11.0
Can verify valet uses php@7.3
Have verified the server is using php@7.3
laravel/valet#728 (comment) (this was a big pain, and a great find)

Have gone through all the possibilities I can find.

This one took a few days to pin down. https://laracasts.com/discuss/channels/code-review/maximum-execution-time-of-30-seconds-exceeded-spatie-medialibrary?page=1#reply=621931

Basically, the policy.xml on imagemagick had a setting for pdf which needed read | write permissions. That was part of it, but also on local I use QUEUE_CONNECTION=sync but that was forcing the conversion so I found changing to redis - at least for this attempt - on local really helped as horizon could take the job...

@freekmurze is it a fair tip on the docs to reference this setting in policy.xml? (for future users of this package and medialibary)

<policy domain="coder" rights="read | write" pattern="PDF" />

Sure, send a PR for this

@freekmurze not sure if the fix I suggested made it through? I thought I forked the README and suggested changes with a PR. Did that work? (first time pr'er)
