TYPO3 Core

When a scheduler task throws an exception, an error is logged.
The log message does not tell us the reason for the failure:

Task failed to execute successfully. Class: TYPO3\CMS\Scheduler\Task\ExecuteSchedulableCommandTask, UID: 23

Now we have error messages that do not tell us anything about the actual error cause, only that something has failed.

Up to TYPO3 v10, this message did include more information:

Task failed to execute successfully. Class: TYPO3\CMS\Scheduler\Task\ExecuteSchedulableCommandTask, UID: 23, Code: 56, OpenSSL SSL_read: Connection reset by peer, errno 104

This behavior was changed (probably unintentional) with patch [BUGFIX] Make logger usage PSR-3 compliant (#94356).
