Hello everybody, i was working on app inventor sources and there I have added a new component, which is my QRCodeGenerator extension, but after doing all the required things told in this guide but as my component is non visible i don't have added Mock view
https://docs.google.com/document/u/0/d/1xk9dMfczvjbbwD-wMsr-ffqkTlE3ga0ocCE1KOb2wvw/pub

But it's showing me error when loading the project and the error is
