使用参数化查询在 postgreSQL 中存储 JSON 个对象

Question

I am having problems with saving JSON objects in the database using parameterized queries. I am using postman to send this object on red.body enter image description here

On my server side I havet his code:

 queryController.createQuery = (req, res, next) => { const { info }= req.body; const sqlQuery = 'INSERT INTO test (info) VALUES ($1) RETURNING *'; db.query(sqlQuery, [info]).then(result => { console.log(result); if (result) res.locals.message = "Saved the query successfully"; next(); }).catch(err => { return next({ log: `queryController.createQuery: ERROR: ${typeof err === 'object'? JSON.stringify(err): err}`, message: { err: 'Error occurred in queryController.createQuery. Check server log for more details.'}, }) })

Why is that I still get this error: enter image description here

throw new TypeError('Client was passed a null or undefined query')
      ^

TypeError: Client was passed a null or undefined query

Here is my table schema:

CREATE TABLE test (
    id serial NOT NULL PRIMARY KEY,
    info json NOT NULL
);

How do I format $1 correctly to get it accept it as JSON file?

Query example:

EXECUTE 'INSERT INTO test (info) VALUES ($1) RETURNING *' USING '[{"size": "Small", "quantity": 1, "product_id": 1}]'::jsonb;
