中的猫鼬API返回了Promise对象，但我正在使用它的回调版本。
insertMany当我对let options = {
"ordered": true
};
MySchema.insertMany(documents, options, function (error, docs) {
if(error) {
// i need insertedIds array here
} else {
// do someting
}
});
对象进行字符串化时，可以看到如下所示的JSON：
error但是当我尝试获取{
"ok":1,
"writeErrors":[
"code":11000,
"index":1,
// there will be some more failure details here
],
"writeConcernErrors":[],
"insertedIds":[
{
"index":0,
"_id":"5be183914d0c761eeadda8c4"
},
{
"index":1,
"_id":"5be183914d0c761eeadda8c5"
},
{
"index":2,
"_id":"5be183914d0c761eeadda8c6"
}
],
"nInserted":1,
"nUpserted":0,
"nMatched":0,
"nModified":0,
"nRemoved":0,
"upserted":[]
}
数组时，它将返回insertedIds。我做了一些研究，发现返回的undefined对象实际上不是JSON对象，而是与error或BulkWriteResult相关的东西。
那么，现在如何获取
BulkWriteError数组中的值？请帮忙。
P.S .：使用猫鼬版本：^ 5.2.17

由于result.insertedIds是吸气剂，请尝试使用let insertedIds = error.result.getInsertedIds()或let insertedIds = JSON.parse(JSON.stringify(error.result)).insertedIds;
