ValueError: The String type doesn't accept collections as value when I upgraded the Adwords API to v201809 and googleads to 14.1.0 and later ones in Python

[Jinesh Mammen]

This was occurred when the python hits stream_data = report_downloader.DownloadReportAsStream(report, skip_report_header=True,

                                                       skip_column_header=False, skip_report_summary=True)

the error is attached to this question. 

report = {'reportName': '********(group by device)', 'selector': {'fields': ['AccountDescriptiveName', 'Impressions', 'Clicks', 'Cost', 'Ctr', ['Device', 'SearchImpressionShare', 'CampaignName']], 'dateRange': {'max': '20190130', 'min': '20190101'}}, 'reportType': 'CAMPAIGN_PERFORMANCE_REPORT', 'dateRangeType': 'CUSTOM_DATE', 'downloadFormat': 'CSV'}

Can someone help me on this?

Thanks in advance.

Hello, I'm getting a similar error when executing the sample code from https://developers.google.com/adwords/api/docs/samples/python/basic-operations#update-a-campaign. This example seems to be broken

Hi Chris,

I was not able to experience any issues with the sample code. Could you provide the error message received or the complete SOAP request and response logs that were generated when you encountered the error? Kindly use the reply privately to author option.
