如何解决“错误

我得到了一些错误，我不知道这是什么意思什么想法吗？这是错误：我不知道是怎么回事，因为我从来没有得到这样的错误之前，我使用res.redirect一样始终。我发现，你应该使用资源。渲染，但我不想被重定向到一个页面不显示页面...

const putOrderToDBAndRedirect = async(res,userId,serviceObj,
                                      ordStart,ordEnd) =>{
    try{
        const result = await pool.query('SELECT id ' +
                                            'FROM orders ' +
                                            'WHERE ($1,$2) OVERLAPS (ord_start,ord_end)',
                                            [ordStart,ordEnd]);
        if(isOverlaping(result)){
            console.log('redirect to page with orders');
            res.redirect('/objednat')
        }else{
            await pool.query('INSERT INTO orders (ord_entered,ord_start,user_id,service_id,ord_end)' +
                                ' VALUES($1,$2,$3,$4,$5)',
                                [new Date(),ordStart,userId,serviceObj.id,ordEnd]);
            const resultArr = await pool.query('SELECT firstname,lastname,phonenumber ' +
                                            'FROM users ' +
                                            'WHERE ' +
                                            'id = $1',[userId]);

            console.log(resultArr.rows[0]);
            const obj = constructOrderObj(serviceObj,ordStart,resultArr.rows[0]);
            res.redirect('/objednano',{orderObj:obj});
        }
    }catch(err){
        console.error(err);
    }

};

你打电话res.redirect('/objednano',{orderObj:obj});但是，这并不符合the function signature for res.redirect()这需要一个可选的状态作为第一个参数和路径作为第二个参数（或路径作为第一个参数，如果只有一个参数，在这种情况下，状态将默认为302 ）。

这是我不清楚你想在那里做什么，说实话。不过，该行的问题。它的治疗的第一个参数状态代码，并'/objednano'显然是无效的HTTP状态。因此，错误消息抱怨HTTP状态无效。
