### Apache Airflow Provider(s) microsoft-azure ### Versions of Apache Airflow Providers >=10.4.0 ### Apache Airflow version 2.10.2 ### Operating System Official Airflow image apache/airflow:2.10.2-python3.12 hosted on AKS ### Deployment Official Apache Airflow Helm Chart ### Deployment details Official Airflow image apache/airflow:2.10.2-python3.12 hosted on AKS ### What happened This issue resembles [Unclosed connector / client session when using asyncio #13242](https://github.com/Azure/azure-sdk-for-python/issues/13242) However, it occurs when triggering an Azure Data Factory pipeline via Airflow using the AzureDataFactoryRunPipelineOperator. Regardless of whether the pipeline completes successfully or fails, the following error is consistently logged: ``` [2025-09-16, 15:08:11 CEST] {base_events.py:1820} ERROR - Unclosed client session client_session: <aiohttp.client.ClientSession object at 0x7f80f1a34380> [2025-09-16, 15:08:11 CEST] {base_events.py:1820} ERROR - Unclosed connector connections: ['[(<aiohttp.client_proto.ResponseHandler object at 0x7f80f1bb1970>, 102727.274540543)]'] connector: <aiohttp.connector.TCPConnector object at 0x7f80f1a34b00> ``` ### What you think should happen instead Displaying the error message is not intended in this context. ### How to reproduce 1. Use AzureDataFactoryRunPipelineOperator to trigger an ADF pipeline. 2. Wait for the pipeline to either succeed or fail. 3. Observe the logs — the error appears regardless of the pipeline outcome. ### Anything else This occurs consistently upon task completion, irrespective of the pipeline's success or failure. ### 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.
