Error log

Hello,

I am using a custom S3 endpoint to back up HA with this integration, and it works, but I regularly see this error in the logs:

2026-02-24 12:25:48.508 ERROR (MainThread) [homeassistant.components.backup] Unexpected error for bauergroup_s3compatiblebackup.01KHW6PW2EXG8NTQGNKXHXKHA4: Task <Task pending name='Task-127381' coro=<S3CompatibleBackupAgent.async_list_backups() running at /config/custom_components/bauergroup_s3compatiblebackup/backup.py:50> cb=[gather.<locals>._done_callback() at /usr/local/lib/python3.13/asyncio/tasks.py:820]> got Future <Future pending> attached to a different loop

It is also reported in the interface:

However, the backup is completed successfully and uploaded to the custom S3.
We can also see that the backup was processed around 5 a.m. and that the errors in the log are at 12:25 p.m. (there may have been some between 5 a.m. and 12 p.m., but I don't know).

AI Analysis

Technical Summary

Technical Requirements and Constraints

1. Environment:
   • A custom S3 endpoint is being used with the bauergroup_s3compatiblebackup integration for Home Assistant to perform backups.
   • The issue occurs in an asynchronous Python-based environment, leveraging libraries such as aiobotocore and aiohttp for S3 operations and streaming.
2. Error Context:
   • The key issue is a RuntimeError caused by a Future being attached to a different event loop.
   • The exception is triggered during the execution of the async_list_backups() coroutine, particularly in the _list_backups method, when attempting to read the metadata_response["Body"].

Implementation Considerations

1. Asynchronous Environment:
   • Proper management of event loop scope is critical. The issue suggests potential mishandling of async/await constructs or task lifecycle, such as cross-thread event loops
