Vue 3 error

[CribbNicolas]

I installed the component, declared it locally and copy the component as in the example and it throws the following error for me.

I also read that Vue 3 support is still being worked on. I just wanted to show the error that it returns to me in console.
Your work looks excellent, I hope one day I will have the ability to program like you.
First of all congratulations and I look forward to compatibility.
