[SOLVED] On accessing properties of payload showing undefined

Hi All,

On accessing properties of payload showing undefined on Appwrite cloud using node.js server sdk

Data:

TypeScript

        messageFor: 'web',
        token: 'test-token',
        userToken: 'test-user-token',
        deviceToken: 'test-device-token'
}```

Sample Code:
```module.exports = async function (req, res) {
  const payload = req.payload;

  res.json({
    messageFor: 'messageFor - ' + payload.messageFor,
    token: 'token - ' + payload.token,
    userToken: 'userToken - ' + payload.userToken,
    deviceToken: 'deviceToken - ' + payload.deviceToken,
  });```

Sample Response:
```{
   "messageFor":"messageFor - undefined",
   "token":"token - undefined",
   "userToken":"userToken - undefined",
   "deviceToken":"deviceToken - undefined"
}```

TL;DR

The user is trying to access properties of a payload but is getting 'undefined' values. It was revealed that the issue was due to the keys in the payload not being wrapped in double quotes. After implementing the necessary changes, the issue was resolved.

On accessing properties of payload showing undefined

req.payload is a string. You'll need to parse it

As per your suggestion, I have implemented the same but getting the below error.

Updated Sample Code

TypeScript

module.exports = async function (req, res) {
  const payload = JSON.parse(req.payload);

  res.json({
    messageFor: 'messageFor - ' + payload.messageFor,
    token: 'token - ' + payload.token,
    userToken: 'userToken - ' + payload.userToken,
    deviceToken: 'deviceToken - ' + payload.deviceToken,
  });

Error Response
