I've been trying to follow the examples and documentation for the python ad_manager library for the google ads API, but I haven't been able to complete a successful request. I currently have my developer token, client_id, client_secret, and refresh_token in my google ads YAML file, but I'm constantly getting the error "argument should be integer or bytes-like object, not 'str'" when calling the function WaitForReport following the example code below. I was wondering if anyone had any advice on how I could tackle this issue.

 import tempfile # Import appropriate modules from the client library. from googleads import ad_manager from googleads import errors def main(client):   # Initialize a DataDownloader.   report_downloader = client.GetDataDownloader(version='v202111')   # Create report job.   report_job = {       'reportQuery': {           'dimensions': ['COUNTRY_NAME', 'LINE_ITEM_ID', 'LINE_ITEM_NAME'],           'columns': ['UNIQUE_REACH_FREQUENCY', 'UNIQUE_REACH_IMPRESSIONS',                       'UNIQUE_REACH'],           'dateRangeType': 'REACH_LIFETIME'       }   }   try:     # Run the report and wait for it to finish.     report_job_id = report_downloader.WaitForReport(report_job)   except errors.AdManagerReportError as e:     print('Failed to generate report. Error was: %s' % e)   # Change to your preferred export format.   export_format = 'CSV_DUMP'   report_file = tempfile.NamedTemporaryFile(suffix='.csv.gz', delete=False)   # Download report data.   report_downloader.DownloadReportToFile(       report_job_id, export_format, report_file)   report_file.close()   # Display results.   print('Report job with id "%s" downloaded to:\n%s' % (       report_job_id, report_file.name)) if __name__ == '__main__':   # Initialize client object.   ad_manager_client = ad_manager.AdManagerClient.LoadFromStorage()   main(ad_manager_client)

    The problem seems to be that zeep raises a WebFault which includes the returned XML response as a string in zeep.Fault.detail.

    Somewhat counter-intuitive, this attribute is not a string, but a bytes sequence because zeep.wsdl.utils.etree_to_string calls etree.tostring() with encoding="utf-8" instead of encoding="unicode"—the latter would make sure it's a proper string.

    googleads then tries to look for specific error strings inside the XML using find(), but even though find() is defined both on str and bytes, the type of the substring to look for needs to align.

    Thus, in

    underlying_exception = e.detail.find( '{%s}ApiExceptionFault' % self._GetBindingNamespace())

    bytes.find() is called with a str argument, causing the ValueError you experience.

    I'd argue that zeep.wsdl.utils.etree_to_string() should be adjusted to actually return a str instead of bytes. You could try opening an issue on Zeep's Github repository.

    In your YAML file, do you have your account number in quotes? (either single or double?)

    Additionally, I would highly recommend not going with this API if you have the option. It will be sunset in April and will no longer work. The newer google ads API (as opposed to the AdWords API) is available, stable and much easier to work with. The ad manager examples are good too.

      I don’t use any quotes in my yaml file. Are they suppose to be in quotes? I’ve also been trying out the ad manager examples (the code mentioned above is one of the examples), but I’m still encountering the issue.
