JSON node list and value error

Hi,

I am having trouble with the JSON Package. I have POST method which is reading first names and last names from a text and responses back to AA360 as a JSON.

When I try to get a node value or node list I get an error.

For some reason my returned JSON looks like so: (I doubt my error message has anything to do with this layout?)

[{"text":"Max Dal Prato","external_id":null,"error":false,"extractions":[{"tag_name":"First Name","extracted_text":"Max","parsed_value":"Max","offset_span":[0,2]},{"tag_name":"Last Name","extracted_text":"Dal Prato","parsed_value":"Dal Prato","offset_span":[4,12]}]}]

My JSON Action:

Any help is appreciated!
