I have python script to download the google ad historical report through the API. I am having below as report job

{       'reportQuery': {           'dimensions': [                          'DATE',                          'MOBILE_APP_NAME',                          'ADVERTISER_NAME',                          'ADVERTISER_ID',                          'AD_UNIT_ID',                          'AD_UNIT_NAME',                          'LINE_ITEM_NAME',                          'LINE_ITEM_ID',                          'LINE_ITEM_TYPE',                          'CREATIVE_TYPE',                          'CREATIVE_NAME',                          'CREATIVE_ID',                          'MOBILE_DEVICE_NAME'                          'PLACEMENT_NAME',                          'PLACEMENT_ID'                          ],           'dimensionAttributes': [                                   'AD_UNIT_CODE',                                   'LINE_ITEM_PRIORITY'                                   'CREATIVE_CLICK_THROUGH_URL'                                     'ADVERTISER_EXTERNAL_ID'                                   ],           'columns': [                      'AD_SERVER_IMPRESSIONS',                      'AD_SERVER_CLICKS',                       'AD_SERVER_CTR',                       'AD_EXCHANGE_IMPRESSIONS',                       'AD_SERVER_CPM_AND_CPC_REVENUE',                       'AD_SERVER_WITHOUT_CPD_AVERAGE_ECPM'           ],           'dateRangeType': 'CUSTOM_DATE',           'startDate': start_date,           'endDate': end_date       }   } 

I am getting below error

Failed to generate report. Error was: [ReportError.COLUMNS_NOT_SUPPORTED_FOR_REQUESTED_DIMENSIONS @ columns; trigger:'AD_EXCHANGE_IMPRESSIONS' 

I am not sure which dimension need to include for AD_EXCHANGE_IMPRESSIONS. When I generate report with same fields in UI it works fine without errors
