Sequelize: column "<column_name>" does not exist (Postgresql)

Question

I Try to query using sequelize into postgres database, but while querying I get the error called: column "createdAt" does not exist Where table looks like:

    Column     |          Type          |
 id            | integer                |
 title         | character varying(200) |
 technologies  | character varying(200) |
 budget        | character varying(20)  |
 description   | text                   |
 contact_email | character varying(100) |
 createdat     | date                   |
 updatedat     | date                   |

Indexes: "gigs_pkey" PRIMARY KEY, btree (id)

Router : gigs.js

import express from "express";
import db from "../config/database.js";
import Gig from "../models/Gig.js";

const router = express.Router();

router.get("/", async (req, res) => {
  try {
    const gigs = await Gig.findAll();
    console.log(gigs);
    res.sendStatus(200);
  } catch (err) {
    console.log(err);
    res.sendStatus(500);
  }
});
export default router;

Models : Gigs.js


import Sequelize from "sequelize";
import db from "../config/database.js";

const Gig = db.define("gig", {
  id: {
    type: Sequelize.INTEGER,
    primaryKey: true,
  },
  title: {
    type: Sequelize.STRING,
  },
  technologies: {
    type: Sequelize.STRING,
  },
  budget: {
    type: Sequelize.STRING,
  },
  description: {
    type: Sequelize.STRING,
  },
  contact_email: {
    type: Sequelize.STRING,
  },
  createdAt: {
    type: Sequelize.DATEONLY,
  },
  updatedAt: {
    type: Sequelize.DATEONLY,
  },
});

export default Gig;

Sequelize try to query 'createdat' and 'updateat' like this:

SELECT "createdAt", "updatedAt" FROM "gigs" AS "gig";

Which is throwing an error

Executing (default): SELECT "id", "title", "technologies", "budget", "description", "contact_email", "createdAt", "updatedAt" FROM "gigs" AS "gig"

Error looks something loke this:

original: error: column "createdAt" does not exist at Parser.parseErrorMessage (D:\Programming\Database\PostgreSQL\Sequelize\node_modules\pg-protocol\src\parser.ts:369:69) at Parser.handlePacket (D:\Programming\Database\PostgreSQL\Sequelize\node_modules\pg-protocol\src\parser.ts:188:21) at Parser.parse (D:\Programming\Database\PostgreSQL\Sequelize\node_modules\pg-protocol\src\parser.ts:103:30) at Socket.

You are talking about postgresql, why do you tag it as mysql?? — nacho

You need to indicate all field names explicitly that differ from model prop names (even if just by letter case):

  createdAt: {
    type: Sequelize.DATEONLY,
    field: 'createdat',
  },
  updatedAt: {
    type: Sequelize.DATEONLY,
    field: 'updatedat'
  },
