原字段的值基础上修改字段

const db=uniCloud.databaseForJQL()

const dbcmd=uniCloud.database().command

async function recharge(event, context,userInfo_token){

let _id =userInfo_token.uid  

let money =event.data.money  



return await db.collection("uni-id-users").where({_id}).update({money:dbcmd.inc(money)})  

}

module.exports={

recharge

}

上面这样吗？

返回下面这样

11:55:25.538 [本地调试]Error: [FailedOperation] multiple write errors: [{write errors: [{Cannot create field 'operands' in element {money: 50}}]}, {<nil>}]
