I understand, but the Preview app ships with a number of plugins, and this is not one of them… so indeed that doesn’t work.

My solution for this issue was to reconfigure the plugin to generate a new firebase.nativescript.json file:

You can reconfigure the plugin by going to the node_modules/nativescript-plugin-firebase and running npm run config.
