Missing manifest.json file?

[arielj]

Branch/Commit:

Main branch.

Expected behavior:

I want to use the app with no errors in the console.

Actual behavior:

Browser console shows an error saying that it failed to fetch assets/favicons/manifest.json. There's this meta tag in the head for some reason <link rel="manifest" href="/assets/favicons/manifest.json">.

Steps to reproduce:

1. Step 1: Open dash
2. Step 2: Check the browser's console
