Ad Performance Report : report null when date is added

[MPM]

Hello,

I'm try to download the AD_PERFORMANCE _GROUP.  v201607

When I define the report:

report_definition = {
    'reportName': 'AD_PERFORMANCE_REPORT',
    'dateRangeType': 'LAST_7_DAYS', #''LAST_7_DAYS',
    'reportType': 'AD_PERFORMANCE_REPORT',
    'downloadFormat': 'CSV',
    'selector': {
        'fields': ['AdGroupId','AdGroupName', 'Date']
    },
}

The field is null. If I take out the field, the file is with data. 

The same happens when I add the CLICKTYPE field. 

any idea?

Hi,

Could you retry this report request by setting the includeZeroImpressions header to true? The ClickType field in this report does not support zero impressions, so rows with zero impressions are not included in the downloaded report.
