Web_teleop demo got stucked in loading page

Hello, we followed instructions of Demo 2 - Web Teleop on Stretch 3.
After launch_interface.sh output is as expected, but neither localhost either remote operator in the same network are not launching the application, there is just continuously spinning wheel “Loading…”.

we right-click on the webpage and click Inspect and share what is being outputted in the console and this is what the console showed:

de9832a04fabe63e7c7b1361f300e8921994×1122 104 KB

then we run the interface launch commands manually and collected logs like the page Web Teleop demo gets stuck loading did.

ros2 launch stretch_web_teleop web_interface.launch.py >> log.txt

log.txt (16.9 KB)

the log shows that there’s something wrong with the realsense2 camera

but when we tried the tutorial Perception - Stretch Docs to test the camera, the terminal shows Stereo is not supported:

the web_teleop worked well a month ago, how to fix that? thanks!

Hi @HaroldMao ,

From the error it looks like there’s an issue with your librealsense package. The best way to address this is by reinstalling it by following these steps:

git clone https://github.com/hello-robot/stretch_install ~/stretch_install
cd ~/stretch_install && git pull
stretch_new_robot_install.sh -u

The -u flag in last command will run a system wide update. This will ensure that there are no conflicting package versions.

Ok I will try to reinstall the librealsense later.
