错误：无效的 BigNumberish 值（参数 =“值”，值 = {“十六进制”：“0xb3e3”，“类型”：“BigNumber”}，代码 = INVALID_ARGUMENT，版本 = 6.7.1）

Question

我尝试将自己的 Gas 值转换为 BigInts、数字、字符串和 JSBI，更改数字值等

我还查看了其他一些答案，但没有解决错误

预期结果：交易通过并批准通过 routerAddress 进行支出

错误：

TypeError: invalid BigNumberish value (argument="value", value={ "hex": "0xb3e3", "type": "BigNumber" }, code=INVALID_ARGUMENT, version=6.4.2)

错误图片：

运行审批功能的代码（错误部分）

// goerli chain
const wethAddress = '0xB4FBF271143F4FBf7B91A5ded31805e42b2208d6';
const routerAddress = '0x68b3465833fb72A70ecDF485E0e4C7bD8665Fc45';

const provider = new JsonRpcProvider(PROVIDER_URL);
const approvalContract = new Contract(wethAddress, erc20Abi, provider);

console.log('approving');
await approvalContract.connect(wallet).approve(
    routerAddress,
    6500000000000000
);
console.log('approved');

如有任何帮助，我们将不胜感激，谢谢！

Answer 1

您看到的错误基本上表明 ethersjs 现在发送了

BigInt

非常规

Number

类型。

您只需将发送的号码解析为

BigInt

即可解决此问题

    const approvalContract = new Contract(wethAddress, erc20Abi, provider);

    await approvalContract.connect(wallet).approve(
    routerAddress,
    BigInt("6500000000000000")
);

对于 ethers.js v6 我会这样写：

    const approvalContract = new Contract(wethAddress, erc20Abi, provider);

    await approvalContract.connect(wallet)["approve(address, uint256)"](
    routerAddress,
    BigInt("6500000000000000"))

请务必检查合约中函数参数的数据类型并按照此处的方式使用它们

["approve(address, uint256)"]
