DAG Run triggered ignoring one missing dataset event

[GiorgosPn]

Apache Airflow version

Other Airflow 2/3 version (please specify below)

If "Other Airflow 2/3 version" selected, which one?

2.10.4

What happened?

We created a DAG, scheduled with 16 different datasets. It ran properly for a couple of days, waiting for all 16 datasets to be produced. But suddenly, it was triggerred ignoring one dataset (triggered taking into account 15/16 datasets).

What you think should happen instead?

The DAG should not be triggered, since only 15 out of 16 datasets were produced at that time.

How to reproduce

We cannot reproduce it, it did not happen earlier and we haven't faced it again some days later.
