[BUG] appConfig undefiend in router.js

[BaconFox]

I'm just getting started with Dashy and had the super basic starting config from Section 3 of quick-start.md. Dashy loaded fine but I never got a chance to dive into the config. I then updated the image to the latest (2.0.9) and found the container would start without error, but Dashy would not load in the browser (Firefox 100).

I noticed the following in the console:

Uncaught TypeError: _a.appConfig is undefined
    41cb router.js:107
    Webpack 8

I do not have appConfig defined in my config.yml, but the docs lead me to believe that should not be necessary.

As long as I define any property in appConfig, even an invalid one such as:

pageInfo:
  title: Home Lab
appConfig:
   someDef: someValue
sections: # An array of sections
- name: Example Section
<snip>

Dashy will load correctly.

Perhaps router.js:107 should be re-written to accept appConfig being undefined or perhaps the default value should be defined earlier for users getting started with very basic configs such as myself?
