DisplayVideo DV360 exitEvents doesn't patch

[davidbonting]

I'm having problems updating the exitEvents of a creative in Google DisplayVideo. I'm able to update all other properties of a creative, except for exitEvents.

Environment details

• OS: macOS Venture 13.1
• PHP version: 7.4.33
• Package name and version: "google/apiclient": "^v2.13.0" & "googleads/googleads-php-lib": "v59.0.0" (Also issue on my last setup: "google/apiclient": "^2.12.6" & "googleads/googleads-php-lib": "^49.0.0")

Steps to reproduce

1. Use the code snippet below, I would expect the exitEvents to update

Code example

use Google_Client;
use Google_Service_DisplayVideo;
use Google_Service_DisplayVideo_Creative;
use Google_Service_DisplayVideo_Dimensions;
use Google_Service_DisplayVideo_ExitEvent;

$client = new Google_Client();
$client->setApplicationName('Example app');
$client->addScope('https://www.googleapis.com/auth/display-video');
$client->setAuthConfig(YOUR_OWN);

$service = new Google_Service_DisplayVideo($client);
$creative = new Google_Service_DisplayVideo_Creative();

$creative->setDisplayName('This is a banner');
$creative->setEntityStatus('ENTITY_STATUS_ACTIVE');
$creative->setHostingSource('HOSTING_SOURCE_THIRD_PARTY');
$creative->setCreativeType('CREATIVE_TYPE_STANDARD');
$creative->setRequireMraid(false);
$creative->setRequireHtml5(false);
$creative->setRequirePingForAttribution(false);
$creative->setNotes('These are notes');
$creative->setThirdPartyTag('<script></script>');

$dimensions = new Google_Service_DisplayVideo_Dimensions();
$dimensions->setWidthPixels(1);
$dimensions->setHeightPixels(1);
$creative->setDimensions($dimensions);

$exitEvent = new Google_Service_DisplayVideo_ExitEvent();
$exitEvent->setType('EXIT_EVENT_TYPE_DEFAULT');
$exitEvent->setUrl('https://google.com');
$creative->setExitEvents([$exitEvent]);

// exitEvents is now
#+exitEvents: array:1 [
#    0 => Google\Service\DisplayVideo\ExitEvent {#5321
#      +name: null
#      +reportingName: null
#      +type: "EXIT_EVENT_TYPE_DEFAULT"
#      +url: "https://google.com"
#      #internal_gapi_mappings: []
#      #modelData: []
#      #processed: []
#    }
#  ]

$result = $service->advertisers_creatives->create(
  YOUR_OWN,
  $creative
 );

// exitEvents is now
#+exitEvents: array:1 [
#    0 => Google\Service\DisplayVideo\ExitEvent {#5290
#      +name: null
#      +reportingName: null
#      +type: "EXIT_EVENT_TYPE_BACKUP"
#      +url: "https://google.com"
#      #internal_gapi_mappings: []
#      #modelData: []
#      #processed: []
#    }
#  ]

$result->setDisplayName('This is a banner with new exitEvent');
$exitEventNew = new Google_Service_DisplayVideo_ExitEvent();
$exitEventNew->setType('EXIT_EVENT_TYPE_DEFAULT');
$exitEventNew->setUrl('https://newsite.com');
$result->setExitEvents([$exitEventNew]);

#+exitEvents: array:1 [
#    0 => Google\Service\DisplayVideo\ExitEvent {#5234
#      +name: null
#     +reportingName: null
#      +type: "EXIT_EVENT_TYPE_DEFAULT"
#      +url: "https://newsite.com"
#      #internal_gapi_mappings: []
#      #modelData: []
#      #processed: []
#    }
  ]

$result = $service->advertisers_creatives->patch(
    YOUR_OWN,
    $result->getCreativeId(),
    $result,
    [
      'updateMask' => 'displayName,exitEvents'
    ]
);

// exitEvents is still the old value while DisplayName has been updated
#+exitEvents: array:1 [
#    0 => Google\Service\DisplayVideo\ExitEvent {#5290
#      +name: null
#      +reportingName: null
#      +type: "EXIT_EVENT_TYPE_BACKUP"
#      +url: "https://google.com"
#      #internal_gapi_mappings: []
#      #modelData: []
#      #processed: []
#    }
#  ]

Even if I would do things differently I can change every value except the exitEvents

$creative = $service->advertisers_creatives->get(
   YOUR_OWN,
   YOUR_OWN
);

$events = $creative->getExitEvents();
$events[0]->setUrl('https://newsite.com');
$creative->setExitEvents($events);

$result = $service->advertisers_creatives->patch(
    YOUR_OWN,
    $creative->getCreativeId(),
    $creative,
    [
      'updateMask' => 'displayName,exitEvents'
    ]
);

I have also played around with exitEvents.url, exitevents, exit_events and so on.

It seems like updateMask doesn't except exitEvents since $creative->setExitEvents([]); would in my eyes result in an error (since it's required) but it doesn't provide an error.

Am I doing something wrong, or is there a bug?
