Laravel - Events - Queued Event Listeners And Database Transactions

When queued listeners are dispatched within database transactions, they may be processed by the queue before the database transaction has committed.

In addition, any models or database records created within the transaction may not exist in the database. If your listener depends on these models, unexpected errors can occur when the job that dispatches the queued listener is processed.
