Trial Service Not Returning Error

[Rodrigo Morales]

Hey guys, we are currently facing an issue regarding Trial Service. Let me add some context. Our application depends on campaign cloning and audience segmentation.

We achieve this by using drafts, trials and trial graduation. For most of our customers we haven't had any problems regarding this method, but right now for one of our customers we have an issue.

When we try to create a trial for campaign 338223296 under account 4199085174 we get the error InternalApiError.UNEXPECTED_INTERNAL_API_ERROR. We tried going deeper but still couldn't retrieve the reason why we get this error.

Initially we thought code without exception catching could give us more info but still nothing. After doing this test we tried creating a draft directly under your UI and got the same error: An unexpected error occurred, please try again later. 

We got a warning regarding ad delivery options, so we changed it from accelerated to normal and ran this set of tests again but still without success ;( We  also thought running procedure synchronously could give us more details. Created a script and ran it, but still got the same error: InternalApiError.UNEXPECTED_INTERNAL_API_ERROR.

This is a very important customer for us, can you please help us check what might be the problem? We tried everything on our side to identify possible errors but found nothing ;( We are currently using API version 201809.

Here's how we make the request:

$trial = new Trial();
$trial->setDraftId($draftId);
$trial->setBaseCampaignId($campaign['id']);
$trial->setName($finalCampaignName . ' - ' . uniqid());
$trial->setTrafficSplitPercent(50);
if ($campaign['advertisingChannelType'] != AdvertisingChannelType: ISPLAY) {
$trial->setTrafficSplitType(CampaignTrialTrafficSplitType::COOKIE);
}
$trial->setStartDate($startDate);
$trial->setEndDate($endDate);
$operations = [];
$operation = new TrialOperation();
$operation->setOperand($trial);
$operation->setOperator(Operator::ADD);
$operations[] = $operation;
/** @var TrialReturnValue $result */
$result = $trialService->mutate($operations);

And here's our SOAP request:

Hi Rodrigo,

Thank you for writing to us regarding your concern related to Trial Service. The InternalApiError.UNEXPECTED_INTERNAL_API_ERROR could be due to a temporary issue in the servers or could be due to a bug. From the shared details, it looks like you tried doing this operation via UI as well and faced the same error. Since API do not add any functionality to the UI, I would recommend contacting the product support team via help icon on the top right corner of your Google Ads account (once logged in) as they will be able to help you with the UI related issues. Once the issue is fixed in the UI, please try the same operation via API and let us know if the issue persists.

Regards,
Nikisha Patel, Google Ads API Team
