Assuming it is for Virtualization. You can write a match script to check if data is null or empty, you can send the default/meta response.

Hi,

We have JSON Filters available. If your JSON Schema is constant and it is not changing then we can go ahead with the existing filter but if it is changing then we will have to write the Script to handle. 

Say your JSON schema is constant. then please use the  JSON Xpath filter as below.

$.GUID[0] = " " Then act accordingly.

Hope this helps.
