JS Sequelize Express Postgres API gives notNull Violation - node.js

Question

Trying to learn sequelize, so I created a small test table and API. I am able to connect to the database and GET data from the API, but I can not insert anything. Sequelize is giving a warning that the value can't be null, even though I'm passing it in.
Call:
{payload=INSERT INTO api.testertab(submission_id, notes) VALUES (6452453223, 'testmessage2');, method=POST}
Basic Table Model:
const getTestertabModel = (sequelize, { DataTypes }) => {
const TT_ret = sequelize.define('testertab', {
submission_id: {
type: DataTypes.TEXT,
allowNull: false,
primaryKey: true
},
notes: {
type: DataTypes.TEXT,
allowNull: true
}
}, {
sequelize,
tableName: 'testertab',
schema: 'api',
timestamps: false,
indexes: [
{
name: "testertab_pkey",
unique: false,
fields: [
{ name: "submission_id" },
]
},
]
});
return TT_ret;
};
export default getTestertabModel;
and routes:
import { Router } from 'express';
const router = Router();
router.get('/', async (req, res) => {
console.log("get all")
const resp = await req.context.models.TT_ret.findAll()
return res.status(200).send(resp);
});
router.post('/upload', async (req, res) => {
console.log("post sub id")
//console.log(req.body)
const resp = await req.context.models.TT_ret.create();
return res.send(resp);
});
export default router;
index.js
import cors from 'cors';
import express from 'express';
import bodyParser from 'body-parser';
import models, { sequelize } from './src/models/index.js';
import routes from './src/routes/index.js';
const app = express();
import dotenv from 'dotenv/config';
app.use(bodyParser.json());
app.use(cors());
app.use(express.json());
app.use(express.urlencoded({ extended: true }));
app.use('/tab', routes.tester);
app.listen(process.env.port, () =>
console.log(`Example app listening on port ${process.env.port}!`),
);
