Fails to load Navigator Component

[Luis Carbonell]

Prerequisites

• Ubuntu 18.04 (Subsystem in Windows 10)
• NativeScript 6.3.3
• Android Version 9
• nativescript-vue-navigator@v0.2.0

Issue Summary

An error is thrown when trying to use the Navigator component as a top-level component. The functionality provided by index.js still works (e.g. this.$navigator.navigate("/some_route")) - but the components/Navigator.js doesn't seem to be imported correctly into my application and a very generic error is thrown.

Stack Trace

Unable to start activity ComponentInfo{org.nativescript.preview/com.tns.NativeScriptActivity}: com.tns.NativeScriptException: Calling js method onCreate failed
Error: Main entry is missing. App cannot be started. Verify app bootstrap.

Additional Information

...would solve myself but the message is incredibly generic; I don't have great debugging tools yet...and I only picked up NativeScript a few weeks ago.

Please help 🙏

After playing around a bit with it...I realized that the Navigator is currently not case or file type sensitive. I had placed app.js and App.vue in the root directory. I simply changed App.vue to Main.vue and the problem was resolved.
