'ReflectionException' while using ReportUtils in Adwords API v201605

[fol...@brainlabsdigital.com]

Hi,

I am trying to use the Adwords PHP API ReportUtils object. 

Here is the code:

$util = new ReportUtils();
// Download report.

$report = $util->DownloadReport($reportDefinition, null, $this->adwordsClient, $options);

The same code works perfectly on the CAMPAIGN_PERFORMANCE_REPORT and on any other report. 

However it doesn't work on the SEARCH_QUERY_PERFORMANCE_REPORT

I had it working previously, but now every time I try to run this code I get the following stack trace:

PHP Notice:  Undefined index: type in /home/foluso/Documents/webProgramming/projects/sqrt/vendor/googleads/googleads-php-lib/src/Google/Api/Ads/AdWords/Util/XmlDeserializer.php on line 136

PHP Fatal error:  Uncaught exception 'ReflectionException' with message 'Property  does not exist' in /home/foluso/Documents/webProgramming/projects/sqrt/vendor/googleads/googleads-php-lib/src/Google/Api/Ads/AdWords/Util/XmlDeserializer.php:138

Stack trace:

#2 /home/foluso/Documents/webProgramming/projects/sqrt/vendor/googleads/googleads-php-lib/src/Google/Api/Ads/AdWords/Util/XmlDeserializer.php(63): XmlDeserializer->ConvertElementToObject(Object(DOMElement))

#3 /home/foluso/Documents/webProgramming/projects/sqrt/vendor/googleads/googleads-php-lib/src/Google/Api/Ads/AdWords/Util/v201605/ReportUtilsDelegate.php(194): XmlDeserializer-> in /home/foluso/Documents/webProgramming/projects/sqrt/vendor/googleads/googleads-php-lib/src/Google/Api/Ads/AdWords/Util/XmlDeserializer.php on line 138

Does anyone know what I could be doing wrong please?

Like I said before, the only thing I change that produces the error, is the name of the report. 

Assume I am passing in no predicates, and only the 'AdGroupId' field into the selector. 

Thanks

I've found the problem that caused this.

It was the include zero impressions flag. 

Not setting it gets rid of the bug. 

Why is that?

[Shwetha Vastrad (AdWords API Team)]

Hi,

Search Query Performance Report doesn't support zero impressions. Setting the includeZeroImpressions header to true will result in ReportDownloadError.ZERO_IMPRESSIONS_REQUEST_NOT_SUPPORTED. This is most likely the reason for the exception you encountered.

Oh wow okay. 

That's great, thank you very much!

It's great that it gives a helpful error, maybe it could be improved if the message could bubble up enough to be in the stack trace?

I say this because I spent a lot of time hunting it down, and if I had seen a single ZERO_IMPRESSIONS_NOT_SUPPORTED, it would have been obvious to me.

I can imagine other developers running into that. 

Perhaps I just missed the error message and I should be looking somewhere else?

Thanks

Foluso

Hi Foluso, 

Are you using the examples provided in the PHP client library? The report download example has try-catch block to handle errors or exceptions that occur while executing the requests. The ReflectionException maybe due to something specific in the client environment. I would suggest that you post this issue in the PHP library's repository as they are better equipped to address this.

Hi Ray,

Please refer highlighted section of this code sample to check out how to set includeZeroImpressions. If not already aware, you may refer this section of the guide for more details. Also, since this thread is quite old, could you please create a new thread if you have any further questions?
