Error - ctor is not a constructor

[Ericky14]

Hello,

I am running into an error when running my app. Does anyone know how to at least debug this to know where it is coming from? Is it a problem with router-outlets not being supported by webpack?

Sorry about that, created with wrong title by accident.

Hey, @Ericky14 were you able to resolve your issue?
If you are still experiencing troubles please post sample project which can reproduce the issue so we could investigate on our side.
if the project is private you can contact me at the community slack - username: niki_iliev

@NickIliev I am still having the same issue. And I am having a completely different issue when I setup a fresh project.

I believe the previous error I got has to do with <page-router-outlet>, but I can't even get this one to run when using NativeScriptCommonModule instead of NativeScriptModule.

I resolved the first issue with ctor is not a constructor. It had with do with the nativescript-barcodescanner plugin.

Initializing that plugin in the constructor argument list caused that error and simply doing this.barcodeScanner = new BarcodeScanner() works.

Not sure if I should close this issue or not since there are errors on that sample app I posted.

Hey, I having the same Issue and I couldn't resolve this, I tried really hard, but no succsess

[Ericky14]

It's most likely an issue with a third party plugin, I suggest trying to uninstall them or install them on an empty package one by one.

[dhagej]

@Ericky14 this was exactly the same issue in my case, you comment really helped me to save time on our production release. Thank you

[stulli103]

Hello hello, I am having similar problems as listed above and I am also using the barcode scanner. Can someone elaborate on how the problems listed above were fixed in a more specific manner.

This is the error I am getting
