Uture opened a new issue, #39602: URL: https://github.com/apache/airflow/issues/39602
### Apache Airflow version 2.9.1 ### If "Other Airflow 2 version" selected, which one? _No response_ ### What happened? After configuring the object storage as XCom backend, the serialization works fine above the specified threshold, but once another task consumes the previously stored XCom, the deserialization doesn't seem to work. Instead, the path of the object is returned instead of the stored data. ### What you think should happen instead? The stored object should be deserialized and returned to the downstream task. ### How to reproduce ``` import pendulum from airflow.decorators import dag, task @dag( schedule_interval=None, catchup=False, start_date=pendulum.datetime(2024, 1, 1, tz="utc"), ) def dag_test(): @task() def producer(): import random return [random.randint(0, 100) for _ in range(10_000)] @task() def consumer(obj): print(obj) producer_t = producer() producer_t >> consumer(producer_t) dag_test() ``` ### Operating System apache/airflow:2.9.0-python3.11 ### Versions of Apache Airflow Providers _No response_ ### Deployment Docker-Compose ### Deployment details _No response_ ### Anything else? _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
