run example [RunInventoryReport], get error

[Mavis00]

Hi,

I need to get revenue report data from API.

I can get the result from example \examples\Dfp\v201702\OrderService\GetOrdersStartingSoon.php successfully. But I got error from the example \examples\Dfp\v201702\ReportService\RunInventoryReport.php, it show error msg as the following:

PHP Catchable fatal error: Argument 1 passed to GuzzleHttp\Psr7\rewind_body() must implement interface Psr\Http\Message\MessageInterface, null given, called in C:\inetpub\wwwroot\dfp_api\src\Google\AdsApi\Common\GuzzleLogMessageHandler.php on line 74 and defined in C:\inetpub\wwwroot\dfp_api\vendor\guzzlehttp\psr7\src\functions.php on line 274

• myOS is windows 7
• the file I ran from browser is http://192.168.200.129/dfp_api/test-RunDeliveryReportForOrder.php, this page is copied from \examples\Dfp\v201702\ReportService\RunInventoryReport.php, and what I only did is changed vender path to "require 'vendor/autoload.php';"

Would you please help me out?

Thanks a lot.

Hi @Mavis00

Sure. We're here to help. :-)

First, could you please confirm the client library version you're using?
Do you use the latest version or a bit earlier version?

The underlying issue would be related to the timeout value. More details can be found in #246.
To fix this, could you please try what's described in this section by setting larger value of timeout?
When the default timeout is too small, the result will not be packed as Response properly and thus null is assigned to $response in this line.

When $response is passed to the function in line 74, it thus fails.
We're also fixing this so that null will not be passed to rewind_body() anymore.

Best,
Knack

I close this issue due to inactivity.
In addition, recently we've refactored GuzzleLogMessageHandler since v27.0.0.
Please update to the latest version and try again.

Best,
Knack
