下载 Metaplex 集合的帐户鉴别器无效

Question

我从锚点 0.17 更新到版本 0.24，从那时起，获取收款帐户失败并出现锚点错误，如下所示： Error: Invalid account discriminator

这是我的代码

export const getCollectionPDA = async (candyMachineAddress: string): Promise<anchor.web3.PublicKey> => {
    return (
        await anchor.web3.PublicKey.findProgramAddress(
            [Buffer.from("collection"), new PublicKey(candyMachineAddress).toBuffer()],
            new PublicKey(CANDY_MACHINE_PROGRAM_V2)
        )
    )[0];
};

const provider = new AnchorProvider(connection, getmywallet(), {
       preflightCommitment: "finalized",
       commitment: "finalized",
});

const idl = await Program.fetchIdl(CANDY_MACHINE_PROGRAM_V2, provider);
const anchorProgram = new Program(idl, CANDY_MACHINE_PROGRAM_V2, provider);

const candyMachineId = "63gzhYWxJ4Yfc5QahLxV6NChSjJZNWW93Sy9CHz8YkCe";
const collectionPDA = await getCollectionPDA(candyMachineId);
const collectionPDAAccount = await connection.getAccountInfo(collectionPDA);

const collectionData = await anchorProgram.account.collectionPda.fetch(new PublicKey(collectionPDA.toString()));

我想知道这是怎么回事。也许集合帐户结构已更新并且区块链包含旧结构？直到最近主播才开始检查这一点？
