1.DApp开发助手（支付宝小程序开发者工具插件）部署/更新合约时，合约仅能部署一次，修改后再次部署失败。

{"type":"returnCode","code":"408 - 123","returnCode":408,"receiptCode":123,"data":{"msg_type":"63","block_number":0,"receipt":{"result":123,"output":"","gas_used":0,"log_entry":""},"transaction_index":0,"return_code":408,"txhash":"0x48539a0c36440ae69997dbb90e423ce8c1c3dc5bdf0164b31bc1a1ee28c7f632"}}

使用JSON解析下

{
    "type":"returnCode",
    "code":"408 - 123",
    "returnCode":408,
    "receiptCode":123,
    "data":{
        "msg_type":"63",
        "block_number":0,
        "receipt":{
            "result":123,
            "output":"",
            "gas_used":0,
            "log_entry":""
        },
        "transaction_index":0,
        "return_code":408,
        "txhash":"0x48539a0c36440ae69997dbb90e423ce8c1c3dc5bdf0164b31bc1a1ee28c7f632"
    }
}

根据文档中错误码的解释：

SERVICE_TX_VERIFY_FAILED

408

transaction verify failed

交易验证失败。

TX_DEST_ACCOUNT_ALREADY_EXIST

123

the dest account of tx already exist

交易的目标账户已经存在。

解决办法：同一合约名，只能存在一个，否则会提示以上错误，故新建合约并重新部署
