Type recognised everywhere but the component

I declared an interface in the

/types

/types

directory. I can use this type in

app.vue

app.vue

and under

/pages

/pages

. However, when I use it in a component, I get:

Unresolvable type reference or unsupported built-in utility type

Unresolvable type reference or unsupported built-in utility type

.
Here is a stackblitz replicating the issue: https://stackblitz.com/edit/github-o4bvcj?file=app.vue
If you comment out the usage of the

TileData

TileData

type in the component it starts to work again even though it's still used in

app.vue

app.vue
