Warning message in Smart Record

I am having the following warning message while using a RTSP stream from a camera. How can I fix this?

** WARN: <queue_src_pad_probe:275>: Invalid PTS found in stream. Stream recorded by Smart Record might have issues

• Hardware Platform (Jetson / GPU): Jetson Orin Nano
• DeepStream Version: 6,3
• JetPack Version (valid for Jetson only): 5.1.2
• TensorRT Version:

It’s just a warning message, telling you that the first frame has arrived and we will add timestamp to it.
