Type string is not assignable to type InferPropType<StringConstructor>

I'm using Vue3 with TypeScript:

```
import { IonIcon } from "@ionic/vue";
import { beer }from "ionicons/icons";

```

but am getting this TypeScript warning:
`Type string is not assignable to type InferPropType`

After some googling I still don't understand what this means. What is a `StringConstructor` type that the icon prop expects?
My code is working but I don't like errors/warnings in my code.
