Describe the bug
I am running NPM using docker-compse. where I ran docker-compose pull and then docker-compose up -d
When the app started, I logged into the new version and instead of having the dashboard/proxy hosts I cannot see anything. I check the Chrome console tab and see a bunch of these:

Reproduce the upgrade with docker-compose pull and docker-compose up -d, then inspect the browser console for the TypeError in 7.bundle.7.js and main.bundle.js?v=2.9.4. Use the linked logs as additional evidence. Done means the dashboard and proxy hosts render after upgrading to version 2.9.4.
