POST請求返回[對象，對象]

我想發送POST請求（使用郵遞員）在我的PostgreSQL數據庫中創建一個條目。但是，目前我的POST請求正在返回[object，Object]，我無法弄清楚原因。POST請求返回[對象，對象]

以下是處理請求的代碼。

//enable the router 
app.use('/', router); 

//Create 
router.post('/api/v1/todos', (req, res, next) => { 
    const results = []; 
    console.log("Congrats you hit the create function!!"); 

    //grab data from http-request, 'complete' is from a boolean value in the database 
    const data = {text: req.query.text, complete: false }; 

    //give error if not recieving a request 
    if(!req.query.text) res.send(400, "The Request data is: " + req.query); 

    //get a prostgres client from the connection pool 
    pg.connect(connectionString, (err, client, done) => { 
    //handle connection errors 
    if (err) { 
     done(); 
     console.log(err); 
     return res.status(500).json({success: false, data: err}); 
    } 

    //SQL Query -> Insert Data 
    client.query('INSERT INTO items(text, complete) values($1,$2)', 
    [data.text, data.complete]); 

    //SQL Query -> Select Data 
    const query = client.query("SELECT * FROM items ORDER BY id ASC"); 

    //Stream results back one row at a time 
    query.on('row', (row) => { 
     results.push(row); 
    }); 

    //After all data is returned, close connection and return the results 
    query.on('end',() => { 
     done(); 
     return res.json(results); 
     //return res.json(data); 
    }); 
    }); 
});
