sequelise with postgreSQL: column doesnt exist

i am trying to make a small webservice with nodejs, express, pogreSQL database using sequelise. Created the database using this in psql

CREATE TABLE Contacts (
    id SERIAL PRIMARY KEY,
    phoneNumber bigint,
    email VARCHAR(255),
    linkedId INTEGER,
    linkPrecedence VARCHAR(20),
    createdAt TIMESTAMPTZ DEFAULT NOW(),
    updatedAt TIMESTAMPTZ DEFAULT NOW(),
    deletedAt TIMESTAMPTZ, 
    FOREIGN KEY (linkedId) REFERENCES Contacts (id)
 );

Defined the contact model in contacts.js as

const { DataTypes } = require("sequelize");
const sequelize = require("./database");

// Define the Contact model
const contacts = sequelize.define(
  "contacts",
  {
    id: {
      type: DataTypes.INTEGER,
      autoIncrement: true,
      allowNull: false,
      primaryKey: true,
    },
    phoneNumber: {
      type: DataTypes.BIGINT,
      allowNull: true,
    },
    email: {
      type: DataTypes.STRING,
      allowNull: true,
    },
    linkedId: {
      type: DataTypes.INTEGER,
      allowNull: true,
    },
    linkPrecedence: {
      type: DataTypes.ENUM("primary", "secondary"),
      allowNull: false,
    },
    createdAt: {
      type: DataTypes.DATE,
      allowNull: false,
    },
    updatedAt: {
      type: DataTypes.DATE,
      allowNull: false,
    },
    deletedAt: {
      type: DataTypes.DATE,
      allowNull: true,
    },
  },
  {
    modelName: "contact",
    tableName: "contacts", 
    timestamps: true,
    freezeTableName: true, // Prevent Sequelize from pluralizing the table name
  }
);

module.exports = contacts;

My webservice receives a post request which has this format

email: example@example.com (string)
phoneNumber: 9999999999 (numbers / int)

In a identifyContact.js file i am trying to find the row which has this email or this phoneNumber and then i process it and send something back. It is giving error at the find.one() method line. The contents of this file are as follows:


const express = require("express");
const contacts = require("./contacts");
const { Op } = require("sequelize");

const router = express.Router();

// Identify endpoint
router.post("/", async (req, res) => {
  try {
    const { email: email_, phoneNumber: phoneNumber_ } = req.body;
    
    // Find the primary contact based on email or phoneNumber
    // getting error at this next line
    const primaryContact = await contacts.findOne({
      where: {
        [Op.or]: [{ email: email_ }, { phoneNumber: phoneNumber_ }],
        linkPrecedence: "primary",
      },
    });

    // If primary contact exists, find secondary contacts linked to it
    if (primaryContact) {
      const secondaryContacts = await contacts.findAll({
        where: {
          linkedId: primaryContact.id,
        },
      });

      // Consolidate the contact information      

      // Send the response
      res.status(200).json({ newContact });
    }
  } catch (error) {
    console.error("Error identifying contact:", error);
    res.status(500).json({ error: "Internal server error" });
  }
});

module.exports = router;

config.js looks like this

module.exports = {
  database: "fluxkart",
  username: "dev1",
  password: "password",
  host: "localhost",
};

database.js

const { Sequelize } = require('sequelize');
const config = require('./config');

// Create a Sequelize instance and connect to the database
const sequelize = new Sequelize(config.database, config.username, config.password, {
  host: config.host,
  dialect: 'postgres',
});

// Test the database connection
sequelize
  .authenticate()
  .then(() => {
    console.log('Database connection has been established successfully.');
  })
  .catch((error) => {
    console.error('Unable to connect to the database:', error);
  });

module.exports = sequelize;

app.js

const express = require("express");
const bodyParser = require("body-parser");
const identifyCustomer = require("./identifyCustomer");

const app = express();

// Middleware
app.use(bodyParser.json());

// Routes
app.use("/identify", identifyCustomer);

// Server
const port = 3000;
app.listen(port, () => {
  console.log(`Server is running on port ${port}`);
});

when i am sending the post request using axios, i am getting an error that says column "phoneNumber doesnt exist"

this is the console after sending request

Executing (default): SELECT 1+1 AS result
Database connection has been established successfully.
example@example.com  ---  1234567890
Executing (default): SELECT "id", "phoneNumber", "email", "linkedId", "linkPrecedence", "createdAt", "updatedAt", "deletedAt" FROM "contacts" AS "contacts" WHERE ("contacts"."email" = 'example@example.com' OR "contacts"."phoneNumber" = 1234567890) LIMIT 1;

}

tldr: sending post request using axois to webservice, which is connected to pg databse and using sequelise ORM, but it gives an error that 'column_name' doesnt exist. But it does! What am i doing wrong? I asked chatgpt too but it says to double check my export and import statements, which didnt help.
