This code will fail because of a typing error:

```auto
export type Card = { (listing of props from prismic document)
    icon: string;
    name: AnyRegularField;
    text: AnyRegularField;
    cta_text: AnyRegularField;
    cta_link: FilledLinkToDocumentField<string, string, never> | FilledLinkToWebField;
};
{slice.items.map(({ icon, name, text, cta_text, cta_link }: Card) => (...)))}

```

On line 9, i am having the error:

```auto
Type 'Record<string, AnyRegularField>' is missing the following properties from type 'Card': icon, name, text, cta_text, cta_link

```

Doing this would fix this error:

```auto
{slice.items.map(({ icon, name, text, cta_text, cta_link }: Record<string, AnyRegularField>) => (...)))}

```

But I don’t want to do this as I would lose the typing of icon for example, which has to be a string in the rest of my code:

```auto
<Icon name={icon} ... />

```

name property of my Icon component has to be of type `string` (and not `AnyRegularField`)

How could I solve this issue knowing that I have to type correctly the props that come from my prismic doc?

Hi Louis,

Could you provide more context? Which line is line 9, and where is the definition for `Record`?
