NativeScript: TypeError: Cannot read property 'navigate' of undefined

Hi,

Since today I had this error on Android and IOS :

01-16 15:30:46.448  6921  6921 E MessageQueue-JNI: 	at com.tns.Runtime.callJSMethodNative(Native Method)

System.err: com.tns.NativeScriptException: 
System.err: Calling js method onTouch failed
System.err: TypeError: Cannot read property 'navigate' of undefined

My code is simply :

import * as frameModule from "tns-core-modules/ui/frame";

var activate = function(args) {
    const navigationEntry = {
        moduleName: "views/activate/activate",
        animated: true,
        transition: {
            name: "slide",
            duration: 380,
            curve: "easeIn"
        }
    };
    var topmost = frameModule.topmost();
    topmost.navigate(navigationEntry); 
};
exports.activate = activate;

The strangest thing is that navigation works for some pages and not for others.

I found that this error could be if the path is not correct, OR my paths are correct (I checked)

TNS -v : 5.0.1
