@@ -37,6 +37,30 @@ When is ``asset_state_store`` available?
When using asset state store within a task, ``context["asset_state_store"]``
is populated for **concrete** :class:`~airflow.sdk.definitions.asset.Asset`
inlets and outlets. A task must declare at least one concrete inlet or outlet
for ``asset_state_store`` to contain any entries.
+If a task has no inlets or outlets and accesses
``context["asset_state_store"]``, a ``KeyError`` is raised at runtime. Declare
at least one asset inlet or outlet on the task to use asset state store.
+
+This applies to both the ``@asset`` pattern and the ``@task`` pattern:
+
+.. code-block:: python
+
+ from airflow.sdk import Asset, DAG, asset, task
+
+ my_asset = Asset("my_data", uri="s3://bucket/my_data")
+
+
+ # @asset DAGs implicitly declare the asset as an outlet
