Hi! I'm currently trying the slicemachine specifically following this guide -\> [Create Navigation Menus with Next.js - Documentation - Prismic](https://prismic.io/docs/navigation-menus-nextjs) and i'm having some trouble with the types definition. After creating the **navigation** slice and the **navigation items** i'm trying to access to the **uid** property of the **Link** field but it seems that the only available field is **slice.primary.link.link\_type** but not **slice.primary.link.uid** (they're available on the response but not in the type definition). I've also added **./.slicemachine/prismicio.d.ts** in my **tsconfig.json** but still no luck; is there any way to add proper types? Thanks! ---

Hello Emiliano, Welcome to the Prismic community, and thanks for reaching out to us. The fields in a slice you can access come under the `data` property, and the UID comes under `results,` so you can not access the UID field. I would like to know more about your use case. Why do you want to access the UID field while creating navigation? I am looking forward to hearing from you back. Thanks, Priyanka ---

Hi, and thanks for the answer! Maybe i didn't explain myself well: ![Screenshot 2023-01-04 at 17.24.53](https://europe1.discourse-cdn.com/flex013/uploads/prismic/original/2X/1/1a7fe96fa439b478bbd6233b4f0cb6ae5f61798d.png) As you can see here in the response, i have the link item, so i can get the **uid** like this: **item.primary.link.uid** ![Screenshot 2023-01-04 at 17.25.05](https://europe1.discourse-cdn.com/flex013/uploads/prismic/original/2X/0/0b043456f486a3ab298d6f229ff8a31719c183ec.png) but for some reason the type only allows to select the **link\_type** property ---

Same thing happen for the Media link; ![Screenshot 2023-01-05 at 15.38.43](https://europe1.discourse-cdn.com/flex013/uploads/prismic/original/2X/e/e048e45dd357b2080d49126c8fb61c6ca1e8385d.png) As you can see from the screen, the api returns an object containing multiple properties, but types only target **link\_type**. I guess in this case the right thing to do do is to use a function to narrow the type, right? ---

Hello @emiliano.bucci Sorry for being delayed reply. That's true that You can access metadata under the link field except for link\_type. That's the expected behavior. Thanks, Priyanka
