Line Chart Visual Discrepancy between Quicksight UI and Web Service

Hi Team,

When I am trying to creating line chart visual from quicksight UI it allows me to add drill down (ie, hierarchy) for axis, color and small multiples but when I try to create the same use web service API it give me below error, is there something I am missing.

Error - 'definition.sheets.1.member.visuals.9.member.lineChartVisual.columnHierarchies' failed to satisfy constraint: Member must have length less than or equal to 2 (Service: AmazonQuickSight; Status Code: 400; Error Code: ValidationException; Request ID: cd7117dc-21e5-4188-9d0c-0780e0873abb; Proxy: null):

UI -

Please note, I have created one sample on quicksight UI, extracted json and tries to created it again using API, it give me error.

Let me know if you need any additional information.
