Ugh! Let me add also, you can see - when the page starts to load after doing:
yarn start -l manifest.json
(I should have told you I was trying to run local mode, ugh)
You can see the page load for a very brief moment and then the error comes up.
I can actually run the host server without a problem. It’s just there’s something stopping the page from loading. I looked into console but… it pretty much has that exact same error. Any ideas?
