                `#{self}.#{name}` cannot be called inside a transaction as this can lead to
                race conditions when the worker runs before the transaction is committed and
                tries to access a model that has not been saved yet.

                Use an `after_commit` hook, or include `AfterCommitQueue` and use a `run_after_commit` block instead.
