getReportJob - Failed to load response into DOM

[jbickum]

Hi Team,

Seeing random issues lately loading responses into DOM and HTTP fetch errors.  This example occurred in the last hour within a minute of the process beginning.  The process executing the report fetch has built-in sleeps to wait out potentially large reports.  In this instance our process ran long enough to check the job status once, slept 30 seconds, and returned these errors after checking the job status a second time.

Any insights greatly appreciated - thanks!

Hello:

That report seems to have completed correctly according to our logs. Can you send me the PHP code you're writing that is running and polling for the status of this report and I'll take a look?

Also, have you been able to reproduce it since then? Or is it still occurring randomly?

Thanks,

Vincent Tsao, DFP API Team

I am getting the same error, for the same API version v201306. This same call occurs in a batch process for a number of line-items, I noticed that the failures seem random -in other words line-items same line-items are not consistently failing, different ones fail each day.

[Vincent Tsao (DFP API Team)]

Can one of you send me the PHP code you're using to run the report and I'll see if I can reproduce it on my side?

Thanks,

Hi Vincent,

    The typical code pattern where this occurs if the following;

CODE

$lineitemService = $this->dfp->GetService('LineItemService', $this->version);

$lineitem = $lineitemService->getLineItem($lineitem_id);

LOG

2014-02-16 03:02:56 AM [DEBUG] [ip: cron, file: controllers/cronjob.php, line: 691] Error Fetching http body, No Content-Length, connection closed or chunked data

#5 /usr/local/shiny/sa/controllers/cronjob.php(691): googledfp->get_campaign_stats(Array, '187028049', '156852129', true)

    This happens in more than one location where I am using the lineitemService. I do know that the lineitem id's exist. Typically it will fail and if you try a few minutes later it will work.

    Let me know if you need more info.

Thanks,
Andre

Hi Andre:

(1) Can you send me the SOAP logs for this as well?

(2) What is your network code?

Thanks,

Vincent, for the last two days, we are getting periodically this connection error once again.  This happens on all DFP calls, not just getReportJob.

It is like the DFP server for v201311 is overloaded and closing the connection.

[Vincent Tsao (DFP API Team)]

This was solved outside the forum, but for posterity:

if you're seeing the error:

"Error Fetching http body, No Content-Length, connection closed or chunked data"

It is an HTTP 1.1 issue with some versions of PHP not properly decoding chunked data (even some versions of PHP 5.3.x will still see this error, the documentation on PHP's official site is wrong). You have two options in this case:

(1) Update your version of PHP to 5.4.x or later.

(2) Force the client library to use HTTP 1.0 by doing the following:

In the file Google/Api/Ads/Common/Lib/SoapClientFactory.php,

right before line 147 where the line says "$options['stream_context'] = stream_context_create($contextOptions);"

add the following line of code:

$contextOptions['http']['protocol_version'] = 1.0;

I will see if there is any check I can do in the client library to prevent this issue.

The second solution removed my problem. This was very weird because we haven't changes anything in a month or so.

Anyhow, thanks a million times! 

[minube]

We had the same problem today, the $contextOptions['http']['protocol_version'] = 1.0; solution solved the problem, but as happened to Mainostoimisto Leimahdus no software updates were made in our servers, so it must be a problem in the API side.

Thanks

[Ops at The Media Trust]

Unfortunately the second solution did not resolve the issue for me.  We also have not made any changes for some time.  Looking at our logs we first encountered the issue between 11:45pm and midnight Eastern time.  All API transactions since that time have failed. This is a major show-stopper - anything that can be done from the API side to resolve this would be greatly appreciated.

Thanks

Hi everyone,

we experienced the same problem today and we were able to fix it by editing the code as indicated.

It must definitely be a problem in the APIs

Thanks

Angelo

We are in the same boat and our API scripts are failing with the same errors. I attempted to apply the HTTP/1.0 fix and it made no difference.

Hello:

In the future please start a new thread, as this thread is 2 years old, and may not be the same issue.

Also, since you're using AdWords, can you please post this to the AW API forums:
