Slot 1: vars.artifacts

Slot 2: json_query

Slot 3: ( " data.results[?type== ' FileHash-MD5 ' ]

Slot 4: value

Exact Extract: “You can assign specific fields from your connector action output to their own variables and further manipulate the data using Jinja filters. This approach allows you to efficiently extract, clean, and prepare information for use in later steps of your automation.”

Exact Extract: The guide shows the same Jinja pattern:

{{ vars.steps.Advanced_Search_Query.data.events | json_query( ' [].attributes.srcIpAddr ' ) | unique }}

and explains that similar Jinja logic applies to extracting other variables from structured output.

The correct expression is {{ vars.artifacts | json_query( " data.results[?type== ' FileHash-MD5 ' ].value " ) }} because the JSON object stores artifact records under vars.artifacts.data.results. Each object in results has a type and a value. The filter condition [?type== ' FileHash-MD5 ' ] selects only records whose type is FileHash-MD5 , and .value returns only the MD5 hash strings, not the full objects.

tojson is unnecessary because the data is already structured and queryable. results, data, and value alone are incomplete because they do not filter by artifact type. The key operation is json_query , which uses a JMESPath-style expression to filter a list and project only the required field.

Technical Deep Dive: This is a classic FortiSOAR playbook parsing pattern. Use json_query when the object is already JSON-like and you know the path. The expression returns a list such as:

[ " 6aad63bcc3dd4e148f3724808955f912 " , " 9fd2b1c0e4a37658bca9d0f1e2c34567 " ]

This is automation-layer data extraction. FortiGate NP/CP offloading is irrelevant because no packet inspection or firewall data-plane forwarding is involved.
