how to insert checkbox as array into mongodb - arrays

Question

I don't know why it's not being inserted. it doesn't show an error or anything so i couldn't figure out the problem.
the tags [ '61c2102d165a5af742091a70', '61c37621165a5af742093a1a' ].
here is my insert function:
insert: async(req,res)=> {
const {userid,tags}=req.body;
console.log("userid", userid)
console.log("tags", tags) //tag [ '61c2102d165a5af742091a70', '61c37621165a5af742093a1a' ]
try {
User.findByIdAndUpdate(
userid,
{ $push: { tags: {$each : tags } }} ,
);
return res.status(200).send({msg:"success"});
} catch (error) {
console.log(error);
res.status(500).send({ msg: "Something went wrong" });
}
}
my user schema:
tags: [{
type: mongoose.Schema.Types.ObjectId,
ref: 'Tag'
}]
tag schema:
const TagSchema = new Schema({
name: {
type: String
},
type: {
type: Object,
},
timestamp: {
type: Date,
default: Date.now
},
});
Most codes i saw do it like that but i couldn't figure out why mine isn't working

Since you are using async, you can make use of await to see it if is saved or not. Rewriting logic in this way you can catch saved instance and return success or failure.
insert: async(req,res)=> {
const {userid,tags}=req.body;
console.log("userid", userid)
console.log("tags", tags) //tag [ '61c2102d165a5af742091a70', '61c37621165a5af742093a1a' ]
const doc = await User.findByIdAndUpdate(
userid,
{ $push: { tags: {$each : tags } }} ,{new:true}
);
if (!doc) return res.status(500).send({ msg: "Something went wrong" });
return res.status(200).send({msg:"success"});
}
