Returning JSON null fields in API responses

Serverless Framework
1

Hi,
I’ve found that when returning an JSON object that has null fields these are not included in the response.
For example if in my handler (node.js) I perform the following:

module.exports.getUserTest = function(event, context, cb) {
var myReturnObject = {
name: “Rick Deckard”,
genre: “male”,
phone: null,
city: null
}

return cb(null, myReturnObject);
}

The response the client gets is:
{
“name”: “Rick Deckard”,
“genre”: “male”
}

How can I return null fields?

Thank you in advance

Not sure how to pass back null values but perhaps you check this in your code?

var test = {
"name": "Rick Deckard",
"genre": "male"
}
console.log(test.phone) // undefined

if (!test.phone) {
  alert('No phone!')
}

Short answer: You can’t

Long answer: JSON doesn’t support null values. You’ll need to use an empty string so something else (that you client understands) to represent a null value.
