Trying to verify a Metaplex NFT as part of a collection

]. 

Here is my code

const collectionAddress = UMIPublicKey("");

const metadata = findMetadataPda(umi, { mint: collectionAddress });
await verifyCollectionV1(umi, {
    metadata,
    collectionMint: collectionAddress,
    authority: umi.identity,
}).sendAndConfirm(umi);

Answer 1

I was forgetting to add the NFT that I wanted to verify and that's why I was getting the error.

The steps to verify a Metaplex collection are

• Mint a collection NFT with the isCollection flag.

• Mint an NFT as part of the collection.

• verify the minted NFT as part of the collection.

const collectionAddress = UMIPublicKey("");
const nftAddress = UMIPublicKey("");

const metadata = findMetadataPda(umi, { mint: nftAddress });
await verifyCollectionV1(umi, {
    metadata,
    collectionMint: collectionAddress,
    authority: umi.identity,
}).sendAndConfirm(umi);
