Why does this window appear?

Which card view are you clicking on?

Because clicking the first card view I saw

gave me the same error.

since I can’t orient myself much in your project I did a test, since you are using

the component must be created dynamically.
and by doing so

I notice that they were created by hand and therefore cannot work.
I recommend you look at some guides on creating dynamic components

Searching the community you will find lots of guides.
