It's About Reusable Content
Your Jinja template likely uses Report Custom Fields, Narrative Sections, and Findings Custom Fields. Calling this data from the PlexTrac application is dependent on proper set-up of this custom reusable data.
The reusable data referenced above is defined through in-platform templates - specifically, the Report Template and the Fields Template.
If you have created a Jinja template, you likely referenced Report Custom Fields, Narrative Sections, and Findings Custom Fields. This section is about making sure that you always have the data structured in congruence with your jinja template data references.
