错误：用原因字符串恢复＆＃x27; blacklistable：帐户被黑名单＆＃x27;

在我的 Hardhat 测试中，我尝试模拟 USDC 账户，以便将 USDC 转移到测试地址。问题是无论我尝试模拟哪个地址，我总是会收到以下错误：

错误：处理事务时虚拟机异常：已恢复，原因字符串“黑名单：帐户已列入黑名单”

以下是相关代码：有关

it("USDC Test", async function () {
    const provider = ethers.provider;
    const USDC = new ethers.Contract(addresses.tokens.usdc, abis.ERC20, provider);

    // Impersonate USDC whale
    await network.provider.request({
        method: "hardhat_impersonateAccount",
        params: [addresses.whales.usdc],
    });
    const usdcWhale = await ethers.provider.getSigner(addresses.whales.usdc);

    // Approve and transfer USDC to test address
    await USDC.connect(usdcWhale).approve(addresses.tokens.usdc, 10000);
    await USDC.connect(usdcWhale).transfer(addresses.test.address1, 10000)
});

如何修复此错误的任何想法？我确信我使用的地址实际上并未被列入黑名单，因为他们最近在 etherscan 上转移了 USDC。

原文

In my Hardhat test I'm trying to impersonate a USDC account so I can transfer USDC to a test address. The problem is no matter what address I try to impersonate, I always get the following error:

Error: VM Exception while processing transaction: reverted with reason string 'Blacklistable: account is blacklisted'

Here's the relevant code:

it("USDC Test", async function () {
    const provider = ethers.provider;
    const USDC = new ethers.Contract(addresses.tokens.usdc, abis.ERC20, provider);

    // Impersonate USDC whale
    await network.provider.request({
        method: "hardhat_impersonateAccount",
        params: [addresses.whales.usdc],
    });
    const usdcWhale = await ethers.provider.getSigner(addresses.whales.usdc);

    // Approve and transfer USDC to test address
    await USDC.connect(usdcWhale).approve(addresses.tokens.usdc, 10000);
    await USDC.connect(usdcWhale).transfer(addresses.test.address1, 10000)
});

Any ideas on how to fix this error? I'm certain the addresses I'm using aren't actually blacklisted considering they recently transferred USDC on etherscan.

我意识到自己的错误。这条线导致了错误：

await USDC.connect(usdcWhale).approve(addresses.tokens.usdc, 10000);

我最初认为我需要批准USDC合同本身来花费我的令牌，但是，如果我只是调用Transfer（）函数，则不需要。

删除此行修复了错误。

I realized my mistake. This line was causing the error:

await USDC.connect(usdcWhale).approve(addresses.tokens.usdc, 10000);

I originally thought I needed to approve the USDC contract itself to spend my tokens, however it's not needed if I'm just calling the transfer() function.

Removing this line fixed the error.
