fieldPath property

For settings with nested fields, if a particular nested field is out of compliance, this specifies the full path to the offending field.

The path is formatted in the same way the policy JSON field would be referenced in JavaScript, that is: 1) For object-typed fields, the field name is followed by a dot then by a subfield name. 2) For array-typed fields, the field name is followed by the array index enclosed in brackets. For example, to indicate a problem with the url field in the externalData field in the 3rd application, the path would be applications[2].externalData.url
