我创建了一个列表，但是在传递和创建列表时，出现了一个错误：

CreateListingRequiresSignerError [MetaplexError]: AuctionHouse > Create Listing Requires Signer
>> Source: Plugin > AuctionHouse
>> Problem: You are trying to create a listing without providing a signer.
>> Solution: Either a seller or authority must be a Signer.

下面是代码本身：

const listing = await metaplex2.auctionHouse().list(
    {
      auctionHouse: auction,
      mintAccount: mintAccount,
      price: price,
      seller: metaplex.identity().publicKey,
    },
    {}
  );

我已经尝试了所有方法，但仍然出现此错误
