SyncClient errors

[jgill-twilio]

I cloned the repo, installed everything, and upgraded the plugin to flex-ui-2.0. I deployed the serverless functions. However, when I try to run twilio flex:plugins:start from the root directory, I am unable to actually interact with the UI. It renders and everything looks great, but I'm unable to update my status, click on tabs, etc.

I checked the console logs and found "Uncaught TypeError: Cannot read properties of undefined (reading 'on')

This is specifically referring to line 12 of /src/services/syncClient.js.

I've tried deleting and reinstalling node_modules and package-lock multiple times, but I keep hitting the same error.
