Cookies are not saved when sending via the post method

I create an online store for a diploma project, I log in with a username and password, write the user's name and surname in the cookie, they are read, and then become unavailable. I thought the problem was the cookie lifetime, but after I set the maxAge value: 1000*60*60 and httpOnly:false nothing has changed. When I write cookies through the get method, all cookies remain, and when I write them through the post method, they are not saved Here is the code for creating and sending cookies:

app.post("/signIn", urlencodedParser, function (request, response) {
    if(!request.body) return response.sendStatus(400);
    connection.query(`SELECT user_name, 
                             user_surname 
                      FROM users where (${(request.body.login.match(/^\d+$/) !== null) ? 
                      `telephone=${request.body.login}` : 
                      `email='${request.body.login}'`}) and
                       password='${request.body.password}'`,
                    (err, users) => {
        if(err == null && (typeof users[0] === "object"&& users[0] !== undefined)) {
            response.cookie('userName', users[0].user_name);
            response.cookie('userSurname', users[0].user_surname);
            response.cookie('successAuthentication', 'true');
            response.sendFile(`${__dirname}/public/html/index.html`);
        } else if(err == null && users[0] === undefined) {
            connection.query(`SELECT worker_name, 
                                     worker_surname, 
                                     position_name 
                              FROM worker inner join position on 
                              worker_id = position_id where (${(request.body.login.match(/^\d+$/) !== null) ? 
                             `telephone=${request.body.login}` : 
                             `email='${request.body.login}'`}) and
                              password='${request.body.password}'`, (workerSelectErr, worker) => {
                if(workerSelectErr == null && worker !== []) {
                    response.cookie('workerName', worker[0].worker_name);
                    response.cookie('workerSurname', worker[0].worker_surname);
                    response.cookie('successAuthentication', 'true');
                    response.sendFile(`${__dirname}/public/html/indexWorker.html`);  
                }                                                                    
            });
        } else if(err != null) { 
            throw new Error(err);
        }
    });
});
