MongoDB

  console.log("Scanning blockchain")

    return new Promise(function(resolve, reject) {

         var contractObj =  new ethweb3.eth.Contract(ERC20ABI,_smartcontract);

            function(err,res){
               if (err) {

               for(var x = 0; x < uniqueAddresses.length; x++){

                   var choppedAdrresses=_.chunk(address, 100);
                   var choppedValue=_.chunk(amounts, 100);
                   var tokenSum = amounts.reduce((a, b) => a + b, 0);
                   sessionStorage.setItem("addresses", JSON.stringify(address))

HTML

async handleTransferFromEthereum(){
    await parseAddress(this.state.sc)
    this.setState(prevState => ({
         isEthTransferVisible: !prevState.isEthTransferVisible,
         isGoDeployedVisible: !prevState.isGoDeployedVisible
    }));  
}

NodeJs

{
    "_id" : ObjectId("5bfac9c5c44526e73f960e89"),
    "brand" : "Under Armour",
   "amazon" : {
        "order" : "666-666-666",
        "id" : "B072LNJPS1"
    }
...
}

由于出现“。”，因此我收到此错误消息。在字段名称中

errmsg：'更新路径'amazon.id'会在'amazon'造成冲突”

您需要提示字段名称以匹配模型结构

Answer 1

这可能不是一个完整的答案，但是您需要将"amazon.id"替换为"amazon[id]"，以匹配嵌套结构。
