Expect

The SRT service reports an error upon startup, and it is unclear what is causing the issue.

When starting, the srt service throws an error, and I don't know what is causing it.

Make sure to maintain the markdown structure.

In short, this is not an Error, but a Warning. The SRT service starts normally, and you can push and pull streams without any issues.

However, this problem needs to be fixed because the printed Error log can cause confusion and interference, making users think that something went wrong.
