EVM:事务已恢复

Question

我在修一座简单的桥。每当我试图在国外的桥梁合同的外国链上存款，它工作得很好。但是每当我试图把令牌存入本地的连锁桥合同。我知道这个错误：

Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending?
Internal JSON-RPC error.
{
"code": 3,
"message": "execution reverted: BEP20: burn amount exceeds balance",
"data": "0x08c379a00000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000002242455032303a206275726e20616d6f756e7420657863656564732062616c616e6365000000000000000000000000000000000000000000000000000000000000"
}

我的桥梁存款功能：

function _deposit(
        address token,      // token that user send (if token address < 32, then send native coin)
        uint256 value,      // tokens value
        uint256 toChainId   // destination chain Id where will be claimed tokens
    ) 
        internal 
        returns (address pair_token) 
    {
        Token memory pair = tokenPair[toChainId][token];
        require(pair.token != address(0), "There is no pair");
        pair_token = pair.token;
        uint256 fee = msg.value;
        if (token <= MAX_NATIVE_COINS) {
            require(value <= msg.value, "Wrong value");
            fee -= value;
        } else {
            if(pair.isWrapped) {
                IBEP20TokenCloned(token).burnFrom(msg.sender, value);
            } else {
                tokenDeposits[token] += value;
                token.safeTransferFrom(msg.sender, address(this), value);
            }
        }
        if (fee != 0) {
            feeTo.safeTransferETH(fee);
            emit Fee(msg.sender, fee);
        }
    }

我的BEP20Cloned薄荷合同。

  // initialize contract. Used instead of constructor in cloned contract
  function initialize(address newOwner, string calldata name, string calldata symbol, uint8 decimals) external {
    require(!_isInitialized, "Already Initialized");
    _isInitialized = true;
    minter = _msgSender();  // set bridge as minter
    emit SetMinter(address(0), minter);
    _name = name;
    _symbol = symbol;
    _decimals = decimals;
    _owner = newOwner;
    emit OwnershipTransferred(address(0), newOwner);
  }

你应该核对一下帐户的余额。那个钱包里似乎没有足够的记号(这通常是当它抛出那个信息时的意思)。你应该把一张支票放在那里，看看余额是否足以支付费用，如果不足够，则恢复。这将给您一个提示，并帮助您调试。
