與 solidity 智能合約交互時出現無效類型 ( struct ) 錯誤

Question

這是錯誤消息：

未捕獲（承諾）錯誤：無效類型（argument="type", value="Proof", code=INVALID_ARGUMENT, version=abi/5.7.0）

這是堅固的功能

function createOffer(
        address _requestorAddress,
        address[] memory _requestedNftAddress,
        uint[] memory _requestedNftId,
        address[] memory _offeredNftAddress,
        uint[] memory _offeredNftId,
        Proof[] memory _proofsRequested,
        Proof[] memory _proofsOffered
)

這是結構

    struct Proof {
        address nftAddress;
        bytes32[] proof;
    }

這是打字稿代碼

    const tx = await contractWithSigner.createOffer(
        address,
        [counter_party_nfts_addresses[0]],
        [counter_party_nft_ids[0]],
        [my_nft_addresses[0]],
        [my_nft_ids[0]],
        [
            [
                counter_party_nfts_addresses[0],
                getMerkelProof(counter_party_nfts_addresses).proof,
            ],
        ],
        [[my_nft_addresses[0], getMerkelProof(my_nft_addresses).proof]]
    );

這是 getMerkleProof 函數：

    const getMerkelProof = (addresses: string[]) => {
        const leaf = keccak256(addresses[0]);
        const leaves = addresses.map((x: any) => keccak256(x));
        const tree = new MerkleTree(leaves, keccak256, { sortPairs: true });
        const proof = tree.getProof(leaf, 0);
        const root = tree.getRoot().toString("hex");
        return {
            proof,
            root,
        };
    };

由於該結構接受兩個參數 1 nftAddress 和 2nd 是 merkleProof，即

[[address,proof]]

但無法找到正確的方法。

Answer 1

    Proof[] memory _proofsRequested,
    Proof[] memory _proofsOffered

參數類型應該是 Proof 結構數組，但您傳遞的是數組數組

      [
        [
            counter_party_nfts_addresses[0],
            getMerkelProof(counter_party_nfts_addresses).proof,
        ],
    ],
    [[my_nft_addresses[0], getMerkelProof(my_nft_addresses).proof]]

反而

    [// convert the inner array to obj
        {
            nftAddress: counter_party_nfts_addresses[0],
            proof    :getMerkelProof(counter_party_nfts_addresses).proof,
        {,
    ],
    [ 
        {
         address: my_nft_addresses[0], 
         proof: getMerkelProof(my_nft_addresses).proof
        }
    ]
