Hello,

tWriteJSONField does not support conditional node creation directly. Conditional logic must be applied before JSON generation.

In tMap, set the output field to null when ID_NUMBER is null or empty:

row1.ID_NUMBER != null && !row1.ID_NUMBER.trim().isEmpty()
? row1.ID_NUMBER
: null

Map this field in tWriteJSONField and enable Remove null fields.
When the value is null, the corresponding JSON node is not created.

Thanks,

Gourav
