复制代码const db = uniCloud.database();
const $ = db.command.aggregate
db.collection('stus')
.aggregate()
.addFields({
Degree: $.add(['$num', 10])
})
.end()
.then(res=>{
console.log(res)
})
.catch(err=>{
console.log(err)
})
报错如下：InternalServerError | errMsg: Command failed with error 40180 (Location40180): 'Invalid $addFields :: caused by :: an empty object is not a valid value. Found empty object at path Degree' on server 192.168.146.77:3717. The full response is { "operationTime" : { "$timestamp" : { "t" : 1623550485, "i" : 10 } }, "ok" : 0.0, "errmsg" : "Invalid $addFields :: caused by :: an empty object is not a valid value. Found empty object at path Degree", "code" : 40180, "codeName" : "Location40180", "$clusterTime" : { "clusterTime" : { "$timestamp" : { "t" : 1623550485, "i" : 10 } }, "signature" : { "hash" : { "$binary" : "Ie20dc8jKYWtYrds8Sdpr+Ham88=", "$type" : "00" }, "keyId" : { "$numberLong" : "6941880109229932637" } } } }
把Degree: $.add(['$num', 10])改为Degree: $.divide(['$num', 10])能正常运行。
请问这是什么原因？

云函数中不存在这个问题，应该是clientDB的bug。不只是add，很多其他运算操作都会报错。望尽快修复。
