Problem during testing (Invalid vnode type)

[alabastor95]

Hi!

Important: the problem is only present when testing!
I am using trying to test this component with vitest. For this, I am mounting it with @vue/test-utils, which throws error.

Example component: <QRCodeVue3 value="https://example.com"></QRCodeVue3>
Problem:

[Vue warn]: Invalid vnode type when creating vnode: undefined. 
  at <ErrorPopup ref="VTU_COMPONENT" > 
  at <VTUROOT>

The component is not created, when console-logging the html part of the wrapper I receive the following in place of it: <!---->
I can successfully mount and test other components.
