Rendering database documents inside the templete, EJS-CodePudding

I cannot render the database documents inside the EJS. It throwing error like "TypeError: req.next is not a function". Piece of code that causing the issue is shown below:

const stockSchema = mongoose.Schema({
  rollingStockNumber: String,
  docs: {
    naturka: String,
    address: String,
    coefficient: String,
    wheel: String,
    weight: Number
  }
});

const Stock = mongoose.model('Stock', stockSchema);
    const stock = new Stock({
      rollingStockNumber: rollingStock,
      docs: {
        naturka: naturkaMinifiedArrayReady[i],
        address: arrayOfWayPlanForm[i],
        coefficient: valueOfCarLength[i],
        wheel: numberOfWheels[i],
        weight: valueOfCarWeight[i]
      }
    });
    stock.save((err) => {
      if (err) {
        res.redirect('/')
      }
    });
};
app.post('/indexReplaced.html', (req, res) => {
  Stock.find({}, function(err, foundStocks){
    if (!err) {
      for (const stock of foundStocks) {
        res.render('indexCalculated', {items: stock.docs.address})
      }
    } else {
      console.log('E', err)
    }
    res.end();
  })
});

Documents inside the MongoDB, there is no problem with inserting them:

Thanks in advance!

Well you are trying to render so many times. Try just rendering one time with the sending addresses objects.

app.post('/indexReplaced.html', (req, res) => {
  Stock.find({}, function(err, foundStocks){
    if (!err) {
      const addresses = foundStocks.map((stock) => stock.docs.address);
      res.render('indexCalculated', {items : addresses}); 
    } else {
      console.log('E', err)
    }
    res.end();
  })
});
