Populate Object Array to Mongoose through API

I'm currently running into issues posting my data with array through the API using Mongoose.

Currently this data is showing in my console:

taskName: 'name',
  word: 'word2',
  wordDesc: 'description',
  tag: [ { text: 'word0' }, { text: 'word1' }, { text: 'word2' } ] }

I need the tag array to be pushed to the database with seperate values, so I can post/target each individual word into HTML for later usage.

Currently I add the whole array into my database collection, which is giving me this data on my database:

"word": "[object Object],[object Object],[object Object],[object Object]"

How do I loop through each item in my array and insert it individually to the database?

API code

 router.post('/task', function (req,res) {
            var task = req.body.tag;
            var taskDesc = req.body.wordDesc;
            var taskName = req.body.taskName;
            console.log(req.body);
            var newTask = new Task ({
                tags:[{word:task}],
                wordDesc: taskDesc,
                taskName: taskName 
            });


            newTask.save(function(err){
                if (err) {
                    return res.send(err);
                }
                return res.json(newTask);
            });
        });

MongoDB Schema

var taskSchema = mongoose.Schema({
    tags: [{
         word        : {type: String, default: ""}
    }],

    wordDesc    : {type: String, default: ""},
    taskName    : {type: String, default: ""}
});
