从 next.js 调用智能合约时，RPC 错误：执行已恢复

Question

I've looked at similar answers regarding this error, and it seems like the majority of them have to do with using the wrong contract address or the abi. In my case, I do not think this is likely because I am using file saver to update contract addresses every time I redeploy and I am using npx hardhat clean before compiling updates to contracts. I've heard some people point out that this error might be due to missing receive() and fallback() functions. In such a case, what is the logic I should put in the functions? I don't quite understand how they work even after reading up on them.

For context, I'm trying to call a deposit function on js.

This is the error I'm getting:

These are the relevant parts of the js:

async function depositToJuniorPool(amount) {
  if (typeof window.ethereum !== 'undefined') {
      const provider = new ethers.providers.Web3Provider(window.ethereum)
      const signer = provider.getSigner()
      const juniorPool = new ethers.Contract(juniorPoolAddress, JuniorPool.abi, signer)
      const usdc = new ethers.Contract(usdcAddress, IERC20withDec.abi, signer)
      console.log('juniorPool: ', juniorPool)
      try {
          await usdc.approve(juniorPoolAddress, amount)
          const val = await juniorPool.deposit(amount)
          console.log('val: ', val)
        } catch (err) {
          console.log('Error: ', err)
        }
}

}

These are the relevant parts for the sol:

  function deposit(uint256 amount) public payable override whenNotPaused withinTransactionLimit(amount) nonReentrant {
    require(amount >= 110, "Must deposit 110 or more");
    uint256 depositShares = getNumShares(amount);
    uint256 potentialNewTotalShares = totalShares().add(depositShares);
    require(poolWithinLimit(potentialNewTotalShares), "Deposit would put the Pool over the total limit.");
    emit DepositMade(msg.sender, amount, depositShares);
    bool success = doUSDCTransfer(msg.sender, address(this), amount);
    require(success, "Failed to transfer for deposit");

    config.getJuniorToken().juniorPoolMintTo(msg.sender, depositShares);
  }


  function juniorPoolMintTo(address to, uint256 amount) public onlyJuniorLendingPool {
    require(canMintForJuniorPool(amount), "Cannot mint: it would create an asset/liability mismatch");
    super._mint(to, amount);
  }

  function doUSDCTransfer(
    address from,
    address to,
    uint256 amount
  ) internal returns (bool) {
    require(to != address(0), "Can't send to zero address");
    IERC20withDec usdc = config.getUSDC();
    return usdc.transferFrom(from, to, amount);
  }

Answer 1

Execution reverted is due to contract call failure. The reverton is either by an accident, for example, when overflow occurs, or intentionally, for example, require() condition is not satisfied.
