No camera data on dashboard when running `.run tracking up`

[shanyu-sys]

Description

When run the application tracking, there is no camera data shown on dashboard

Also "http://localhost:5002/video?" is always loading (without any data).

More information:

• The application "haidetection" works normally.
• By using server2.py, instead of server1.py in the producer service of docker-compose.yml, it works fine.

It seems server2.py is a refactored version of server.py, whose application streams code have been well-decoupled. Will we replace the server.py with server2.py for all the applications?

Expected Behavior

Camera data shows the annotated video stream on dashboard.

Actual Behavior

Camera data is empty.

Affected Version

Tested on the "main" branch

Steps to Reproduce

run .run tracking up
