`undefined` is missing from exported JSON #7

Open nkooman-bzs opened 1 month ago

nkooman-bzs commented 1 month ago

Brief bug description

When data is exported any fields that are set to undefined will not be present in the resulting JSON output.

Repro steps

  1. Export a content item that includes an empty field
    • Ex: Non-required number element or text element
  2. Run the export command
  3. See that the value field does not exist

Expected behavior

The value field has a value.

Test environment

N/A

Additional context

undefined is not a valid value per the JSON specification.

The import will gracefully handle a missing value field. Accessing data.value when value is missing still results in undefined. However, this can cause issues when a user wishes to directly interact with the exported JSON, expecting the value field to exist. Also, values of 0 and an empty string will not be imported correct, resulting in incorrect migrations.

I believe the fix to this issue would be to use null instead of undefined to represent an empty field.
