}

I have 2 documents one is issue and other is a label. Issue has one to many relation with the label schema. so my schema for label looks like this

 labels:[{
        type:mongoose.Schema.Types.ObjectId,
        ref:'Label'
    }],

the issue is i don’t get the error when i insert a single value in the labels using this
code

 issues.labels.push(allLabelsWithId);

here allLabelsWithId is a array. But this array when have value more than 1 it fails and give the error mentioned above.

I need to pass multiple values so what is the correct way of doing it.
