"argument should be integer or bytes-like object, not 'str'"

[Edmond Poon]

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)

Below is the stack trace:

Hello, thanks for the report! While I was not able to reproduce your issue, a quick look shows that this is being raised by Zeep when processing an error in the API response. It seems like the "Unknown fault occurred" message is specified when Zeep can't parse the error response to find the Fault information.

Other error messages are correctly parsed, but it seems like the specific one you're encountering is not, which of course makes it more difficult to determine what caused the API call to fail. Given that, I don't think there's much we can do here on the client library side–I recommend reaching out to the Ad Manager support forum to:

1. Determine why your API call really failed.
2. Report that the fault message for that particular error case doesn't appear to be parseable.

Regards,
Mark

Hi. I've encountered the same problem with googleads==38.0.0.

It fails on this line:

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

e.detail contains a byte string

b'<?xml version=\'1.0\' encoding=\'utf-8\'?>\n<HTML>\n<HEAD>\n<TITLE>Unauthorized</TITLE>\n</HEAD>\n<BODY BGCOLOR="#FFFFFF" TEXT="#000000">\n<H1>Unauthorized</H1>\n<H2>Error 401</H2>\n</BODY>\n</HTML>'

Python documentation contains the following information:

The subsequence to search for may be any bytes-like object or an integer in the range 0 to 255.
