Additional information

This is new in 2.4.8

A quick look at the code and it would appear that the cron job name has been changed to product_alert in 2.4.8 but the path to the cronjob config has not been changed to match the new job name.

magento2/app/code/Magento/ProductAlert/etc/crontab.xml

Lines 10 to 12 in 73d7bd4

	<job name="product_alert" instance="Magento\ProductAlert\Model\Observer" method="process">
	<config_path>crontab/default/jobs/catalog_product_alert/schedule/cron_expr</config_path>
	</job>

Debugging the generateSchedules code shows that an extra job is added to the jobs list with incomplete contents, with the name of "catalog_product_alert" which is causing the error.

The correct "product_alert" jobs are scheduled and run correctly, so this is just an annoyance more than anything having a failed erroneously scheduled job run every day.

Release note

erroneous "catalog_product_alert" cron jobs are no longer scheduled after "product_alert" job name change.
