JSON serialization in API responses omits fields with undefined
value to follow the JSON specification. According to the JSON standard, properties with undefined
values are not allowed in JSON objects, these are the allowed JSON values: object
, array
, number
, string
, true
, false
, or null
.
We need to be mindful while handling the missing data. On the backend, use null
or defaults for missing data. On the frontend, ensure data is present before accessing it.
