Theme app extensions store 2.0 try again later

[Bogdan_Hiriscau]

I've recently updated my app to be compatible to the Online Store 2.0 features. The theme extension is created and works perfect on a fresh install of the app on a store with Dawn theme.

However when switching from a legacy theme to a fresh new 2.0 theme, the app blocks do not work anymore.

This issue seems to happen both for the app i'm testing with, but also with other apps including Shopify's Product Review app.

The error is :

And from the console under the network tab I can see this:

{"errors":[{"message":"Internal error. Looks like something went wrong on our end.\nRequest ID: 35dcd60b-6aae-4ba9-8eb7-294c39012fc1 (include this in support requests).","extensions":{"code":"INTERNAL_SERVER_ERROR","requestId":"35dcd60b-6aae-4ba9-8eb7-294c39012fc1"}}]}
