And the problematic code block

async with self._client(max_attempt=max_attempt, backoff_factor=5, retry_status=DEFAULT_RETRY_STATUS + [500]) as client:
			await LOGGER.ainfo("Try to call mediaMTX API")
			response: httpx.Response = await client.post(
				f"/v3/config/paths/add/{stream_id}", json={"name": str(stream_id), "source": str(rtsp)}
			)

			match response.status_code:
				case 200:
					await LOGGER.ainfo("Successfully registered stream, wait for 1s", stream_id=str(stream_id))
					await anyio.sleep(1)
				case 400:
					await LOGGER.awarning("Stream is already existed", stream_id=str(stream_id))
				case _:
					try:
						response.raise_for_status()
					except Exception as e:
						raise StreamOperationFailed(f"Failed to register stream (ID: {stream_id})") from e
