I think I'm having a similar issue. The following query for customer ID 763-523-8060 and API version v201607, without a label filter, works:
SELECT Cost,Labels FROM CAMPAIGN_PERFORMANCE_REPORT DURING 20160912,20160918 And this one, with a label filter, doesn't work: SELECT Cost,Labels FROM CAMPAIGN_PERFORMANCE_REPORT WHERE Labels CONTAINS_ALL ["PLAs"] DURING 20160912,20160918 It results in this error: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <reportDownloadError> <ApiError> <type>ReportDownloadError.ERROR_GETTING_RESPONSE_FROM_BACKEND</type> <trigger>Unable to read report data</trigger> <fieldPath></fieldPath> </ApiError> </reportDownloadError> Please let me know if more information would be helpful.
