ReportDownloadError.ERROR_GETTING_RESPONSE_FROM_BACKEND when I use "CONTAINS_NONE"

[flo...@ikom.fr]

Hello,

I have some problems with the use of the "CONTAINS_NONE"or other "CONTAINS_*" predicates operator on "Labels" fields when I try to download report from "CAMPAIGN_PERFORMANCE_REPORT" with the php lib.?

Here the code : 

$selector = new \Selector();
if($label !== null){
    $selector->predicates[] = new \Predicate('Labels', 'CONTAINS_NONE', '[\''.$label.'\']');
}
$selector->fields = array('Month', 'Clicks', 'Impressions', 'Ctr', 'AverageCpc', 'Cost', 'AveragePosition', 'Conversions', 'CostPerConversion', 'ConversionRate', 'ConversionValue', 'ValuePerConversion');
$selector->dateRange = new \DateRange($dateStart, $dateEnd);
$reportDefinition = new \ReportDefinition();
$reportDefinition->selector = $selector;
$reportDefinition->reportName = 'Campaign performance report #'.uniqid();
$reportDefinition->dateRangeType = 'CUSTOM_DATE';
$reportDefinition->reportType = 'CAMPAIGN_PERFORMANCE_REPORT';
$reportDefinition->downloadFormat = 'CSV';
$options = array();
$options['version'] = 'v201603';
$options['skipReportHeader'] = true;

And here the result :

Response Code: 500
Error Message: Report download failed. Underlying errors are

Why I get this error ?

Thanks.

Hi, 

I noticed you didn't select the field "Labels". Could you add that field and try again? 

Thanks,

Hi, 

Thanks for your response, I have found my error. I search by labelName, not by labelId so I have this error. 

Best regards,
