Hi guys. I am learning cadence by tutorial. I have some misunderstanding in the 4th part (Non-Fungible Tokens). I want to add some extra information in NFT resource. I add some property “meta” in this resource and I created func to get this property (“return self.ownedNFTs[i].meta”), but I face with error **“value of type `ExampleNFT.NFT?` has no member `meta`. unknown member”.** The same for id. How can I grant access to see variable in resource? The link to this tutorial: [Flow Playground](https://play.onflow.org/afda15d7-5c7d-49a4-8ed2-c8f8addddaa6?type=account&id=e103c161-8a92-4bc4-bb31-4536cf1e3b74). The contract // NFTv2.cdc in the second account.

Your type here is an optional, so you need to unwrap it before accessing the field. See my blog post for more information about optionals: [Optionals in Cadence? Not Optional! | by Joshua Hannan | Apr, 2021 | Medium](https://joshuahannan.medium.com/optionals-in-cadence-not-optional-fb39bb4b0081)
