Magento 2.4 Bulk Updates Not Working Or Appearing In The Action Log

Is your Magento store just not processing bulk updates to prices or attributes ? Your consumers are running and cron jobs seem to be running ok.

We came across this issue – and it took weeks to figure out. There are loads of articles about the bulk actions just stating “Not Started” but what if they don’t make it into the magento_bulk database table in the first place ?

bin/magento queue:consumers:start --max-messages=100 --batch-size=1000 product_action_attribute.update

If you run this command and check the system.log immediately after it completes, do you see
