即使出现“内部错误”，Rest API 也会返回状态代码 201

Question

When a do a POST request with no body data it should return a status code 400, but it's returning a status code 201 with an empty object.

This the code:

router.post('/', (req: Request, res: Response) => {
const transaction = new Transactions({
    name: req.body?.name,
    amount: req.body?.amount,
    type: req.body?.type,
})
try{
    const newTransaction = transaction.save();
    return res.status(201).json(newTransaction);
}catch (err){
    return res.status(400).json({message: err.message});
}
})

This is the postman request and the response:

This looks like mongodb and mongoose. .save() returns an promise and should be resolved. You can do it with async / await here. What you return as an response is an pending promise.

router.post("/", async (req: Request, res: Response) => {
  const transaction = new Transactions({
    name: req.body?.name,
    amount: req.body?.amount,
    type: req.body?.type,
  });
  try {
    const newTransaction = await transaction.save();
    return res.status(201).json(newTransaction);
  } catch (err) {
    return res.status(400).json({ message: err.message });
  }
});
