I am getting the same error. I created a test-DAG to connect to my S3 bucket and list the file names. It throws the exact same error. ```python [2025-08-27, 14:06:14] ERROR - Task failed with exception: source="task" NotImplementedError: Objects of type <class 'pydantic_core._pydantic_core.SerializationIterator'> are not supported File "/home/airflow/.local/lib/python3.12/site-packages/airflow/sdk/execution_time/task_runner.py", line 918 in run File "/home/airflow/.local/lib/python3.12/site-packages/airflow/sdk/execution_time/task_runner.py", line 1213 in _execute_task File "/home/airflow/.local/lib/python3.12/site-packages/airflow/sdk/bases/operator.py", line 397 in wrapper File "/home/airflow/.local/lib/python3.12/site-packages/airflow/sdk/bases/decorator.py", line 251 in execute File "/home/airflow/.local/lib/python3.12/site-packages/airflow/sdk/bases/operator.py", line 397 in wrapper File "/home/airflow/.local/lib/python3.12/site-packages/airflow/providers/standard/operators/python.py", line 217 in execute File "/home/airflow/.local/lib/python3.12/site-packages/airflow/providers/standard/operators/python.py", line 240 in execute_callable File "/home/airflow/.local/lib/python3.12/site-packages/airflow/sdk/execution_time/callback_runner.py", line 81 in run File "/opt/airflow/dags/minio_example_with_hook.py", line 23 in list_s3_bucket_contents File "/home/airflow/.local/lib/python3.12/site-packages/airflow/providers/amazon/aws/hooks/base_aws.py", line 839 in get_conn File "/usr/local/lib/python3.12/functools.py", line 998 in __get__ File "/home/airflow/.local/lib/python3.12/site-packages/airflow/providers/amazon/aws/hooks/base_aws.py", line 774 in conn File "/home/airflow/.local/lib/python3.12/site-packages/airflow/providers/amazon/aws/hooks/base_aws.py", line 676 in region_name File "/usr/local/lib/python3.12/functools.py", line 998 in __get__ File "/home/airflow/.local/lib/python3.12/site-packages/airflow/providers/amazon/aws/hooks/base_aws.py", line 638 in conn_config File "<string>", line 9 in __init__ File "/home/airflow/.local/lib/python3.12/site-packages/airflow/providers/amazon/aws/utils/connection_wrapper.py", line 201 in __post_init__ File "/home/airflow/.local/lib/python3.12/site-packages/airflow/sdk/definitions/connection.py", line 162 in extra_dejson File "/home/airflow/.local/lib/python3.12/site-packages/airflow/sdk/execution_time/secrets_masker.py", line 130 in mask_secret File "/home/airflow/.local/lib/python3.12/site-packages/airflow/sdk/execution_time/comms.py", line 187 in send File "/home/airflow/.local/lib/python3.12/site-packages/airflow/sdk/execution_time/comms.py", line 145 in as_bytes File "/home/airflow/.local/lib/python3.12/site-packages/airflow/sdk/execution_time/comms.py", line 122 in _msgpack_enc_hook ``` -- This is an automated message from the Apache Git Service.
