Property 'run' does not exist on type 'Promise<FindNftsByOwnerOutput>'

Question

I want to get Nft data from metaplex but i wanna know what does .run() work here and why .run() method does not exist here

const nfts = await metaplex.nfts().findAllByOwner({owner: args.publicKey,}).run()

nfts.forEach(nft => { metaplex.nfts() .load({metadata: nft}) .run() .then(loaded => console.log(loaded))

Answer 1

run() is only necessary for builders, not for operations. Builders are available for operations that write to the chain, and allow several operations to be combined into a single transaction.

See:

• NftClient
• NftBuildersClient

Answer 2

The @metaplex-foundation/js package is also now deprecated in favor of, UMI (Unified Metaplex Interface)

See repo here https://github.com/metaplex-foundation/umi
