A parsed copy of the field path. For example, the field path "operations[1].operand"
corresponds to this list: {FieldPathElement(field = "operations", index = 1),
FieldPathElement(field = "operand", index = null)}.
trigger
xsd:string
The data that caused the error.
errorString
xsd:string
A simple string representation of the error and reason.
