Card Refuses to Connect, JSON response Invalid Error when npm start

There was an error rendering this rich post.

I have a domo app that I am trying to dev from linux with npm. I do a domo login and domo publish and the app publishes up to the env. Then I create a card and it gives me error

788b03b5-032c-4a1a-8c62-205afaa3a349.domoapps.prod5.domo.com

refused to connect.

If I try to use the app from npm start on dev computer, then I cannot hit the empty collections. Sidenote: I did have to create the collections when I created the card.

Did you add the proxyId to the manifest.json? https://developer.domo.com/portal/af407395c766b-the-manifest-file#getting-a-proxyid-advanced

Yes, I did, thanks for the feedback. Two items helped solve the issue, use domo template for react app and instead of domo publish, use npm run upload. This seems to be a new way to publish versus the older method.
