Accessing triggering asset events with Jinja
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+.. note::
+
+ In Airflow 3.1.x, the ``source_dag_run`` attribute of ``AssetEvent`` is not
+ exposed to Jinja templates, and attempting to access it will result in a
+ template rendering error.
+
+.. versionadded:: 3.2.0

You can use Jinja templating to pass information from the triggering asset
events to your operators.
