'void com.getcapacitor.Bridge.onStart()' on a null object reference

Question

I am wrapping a React application into Capacitor. When I run it from AndroidStudio the application starts and stops immediately. I receive the following.

E/AndroidRuntime: FATAL EXCEPTION: main
    Process: com.example.app, PID: 20226
    java.lang.NullPointerException: Attempt to invoke virtual method 'void com.getcapacitor.Bridge.onStart()' on a null object reference

It seems that something absent. I checked tutorials. @capacitor/core is present.

Answer 1

I was able to fix this issue by downgrading @capacitor/cli to v2.4.5.

npm i @capacitor/[email protected]

I was facing issue with v3.0.1.
