When I try to open my apps that have Push notifications with the app `Fuse Preview` I get this error:

Yes, as mentioned [in the docs](https://www.fusetools.com/docs/basics/preview-and-export#fuse-preview-app) the push notification package is not supported in the stand-alone preview app.

You can instead build your own custom preview (e.g. “the regular preview”) for testing those projects.
