I happened to error when roslaunch

[wahihi]

Hi Thien.
I make drone with your blog.
https://discuss.ardupilot.org/t/precision-landing-with-ros-realsense-t265-camera-and-apriltag-3-part-2-2/51493

I was roslaunch, some roslaunch is good. But some roslaunch is show the error message.

Do you read my error message. and give me some advice?
And my system is not equal your system.

I change to right.

Mission Computer : Raspberry Pi --> Jetson Nano
Flight Control : ardupilot ----> PX4

1 roslaunch realsense2_camera rs_t265.launch --> [Good]
2 roslaunch vision_to_mavros t265_fisheye_undistort.launch --> [Error]
3 roslaunch apriltag_ros continuous_detection.launch --> [Error]
4 roslaunch vision_to_mavros t265_downfacing_tf_to_mavros.launch --> [Good]
5 roslaunch mavros apm.launch --> [Good]
