NodeJS Express Mongoose return empty []
You should fix the Controller (VulcanoSchema.find needs an empty object as parameter):
Controller file:
const VulcanoSchema = require('../models/vulcano.models');const getAllVulcanoes = (req, res) => { VulcanoSchema.find({}, (err, results) => { if (err) { console.log(err); res.status(500).json({message: err}); } else { res.status(200).json(results); } });};module.exports = {getAllVulcanoes};
