Hello! I've recorded a rosbag using the intel realsense depth camera D455. I'm playing the rosbag in one terminal on loop and trying to initialize a pyrealsense2 pipeline but I get the following error:

RunTimeError: Failed to resolve request. Request to enable_device_from_file("testBag.bag") was invalid, Reason: Failed to create ros reader: Invalid file fromat, file does not contain topic "/file_version" nor "/FILE_VERSION"

Here's a code snippit from where the error occours:

import rospy import cv2 import pyrealsense2 as rs from sensor_msg.msg import Image from cv_bridge import CvBridge def process_image(msg): pipeline = rs.pipeline() cfg = rs.config() cfg.enable_device_from_file("testBag.bag") profile = pipeline.start(cfg)

Thanks in advance for any help I can get!
