Web UI has significant delay when responding to selection of route

[MishkaMN]

Summary

This was first discovered on Black Pacifica during preparation for HASS demo on 06/11/2024 (https://usdot-carma.atlassian.net/browse/CAR-6037).
After starting carma and web ui, the route selection doesn't go through immediately. It looks like the web-ui is not even responding. It takes restart of the web-ui and more than 15s+ waiting for it to actuall get registered.
Due to its inconvenience, I had to use command line scripts to route select and engage which works fine.

interestingly, fusion doesn't have this problem but also I seen this issue on my local VM when I ran carma-config:carma-system-4.5.0-development version.

I also see this error, which I am not sure if it is related.
This makes me wonder if there is a common configuration between the two carma-config or the two environments that is causing this significant delay.

Version

Expected Behavior

Actual Behavior

Steps to Reproduce the Actual Behavior
