Serializing exceptions causes fatal error when exception_ignore_args is disabled

[matthi4s]

When throwing an exception in a task, the exception is serialized and sent back to the parent process. When exception_ignore_args is disabled, this exception also includes arguments that cannot and should not be serialized.

An error like this is thrown:

PHP Fatal error:  Uncaught Exception: Serialization of 'Closure' is not allowed in vendor/aternos/taskmaster/src/Communication/Socket/Socket.php:46

(This error can also occur for other reasons)

You can check your current php.ini setting using

php -i | grep "exception_ignore_args"

For now, the easiest fix is to enable exception_ignore_args in your php.ini.

A better solution would be removing all args from exceptions when serializing in Taskmaster.
