Head commit for run: 612bb9295ede5206f47f7555a61af59db47ad204 / Kaxil Naik <[email protected]> Fix DAG deserialization failure with non-default ``weight_rule`` Resolves an issue where DAGs using non default value like `weight_rule='absolute'` would fail during deserialization with `'Unknown priority strategy'` error. The problem occurred when the scheduler attempted to deserialize tasks that had already been converted to `PriorityWeightStrategy` instances. The `validate_and_load_priority_weight_strategy` function now properly handles cases where a `PriorityWeightStrategy` instance is passed, returning it directly instead of attempting to re-validate it. This fix ensures that all weight rule options (`downstream`, `upstream`, `absolute`) work correctly in the complete DAG processing pipeline including serialization, storage, and deserialization. To Reproduce the bug, run the following dag or just run the added unit test without code changes: ```py from airflow import DAG from airflow.sdk import task from airflow.task.weight_rule import WeightRule with DAG("xcom_backend_dag"): @task() def xcom_producer(): return "my_value" @task(weight_rule=WeightRule.ABSOLUTE) def xcom_consumer(value): assert value == "my_value" xcom_consumer(xcom_producer()) ``` which will then fail, when you try to trigger the dag from UI.
