Invalid parameter Facebook video ad creative in Facebook Marketing API - php

Question

I am getting the same error while creating Ad Creative via Facebook Marketing API. I followed their guide but doesn't work. Facebook video ad creative reference
$config = Config::get('facebook');
$data['account_id'] = 'act_'.$config['ad_account_id'];
$data['page_id'] = $config['page_id'];
// Init facebook
$api = Api::init($config['app_id'], $config['app_secret'], $config['access_token']);
// Create product catalog
$product_catalog = new ProductCatalog(null, $config['business_id']);
$product_catalog->setData(array(
ProductCatalogFields::NAME => "Catalog",
));
$product_catalog->create();
$product_catalog_id = $product_catalog->id;
// Setup Feed
$product_feed = new ProductFeed(null, $product_catalog_id);
$product_feed->setData(array(
ProductFeedFields::NAME => 'Campaign Feed',
ProductFeedFields::SCHEDULE => array(
ProductFeedScheduleFields::INTERVAL => 'DAILY',
ProductFeedScheduleFields::URL => 'http://example.com/facebook/dpa_product_catalog_sample_feed.csv',
ProductFeedScheduleFields::HOUR => 22,
),
));
$product_feed = $product_feed->create();
// Create Product Set
$product_set = new ProductSet(null, $product_catalog_id);
$product_set->setData(array(
ProductFeedFields::NAME => 'All Product',
));
$product_set->create();
$data['product_set_id'] = $product_set->id;
$video = new Advideo(null, $data['account_id']);
$video->{AdVideoFields::SOURCE} = public_path().'/facebook/video-demo.mp4';
$video->create();
$video_data = new AdCreativeVideoData();
$video_data->setData(array(
AdCreativeVideoDataFields::IMAGE_URL => 'http://example.com/facebook/resize-image.jpg',
AdCreativeVideoDataFields::VIDEO_ID => $video->id,
AdCreativeVideoDataFields::CALL_TO_ACTION => array(
'type' => AdCreativeCallToActionTypeValues::LIKE_PAGE,
'value' => array(
'page' => $data['page_id'],
),
),
));
$object_story_spec = new AdCreativeObjectStorySpec();
$object_story_spec->setData(array(
AdCreativeObjectStorySpecFields::PAGE_ID => $data['page_id'],
AdCreativeObjectStorySpecFields::VIDEO_DATA => $video_data,
));
Above these code working and return response but when I call ad creative, the API return "Invalid parameter"
$creative = new AdCreative(null, $data['account_id']);
$creative->setData(array(
AdCreativeFields::NAME => 'Video Ad Template Creative Sample',
AdCreativeFields::OBJECT_STORY_SPEC => $object_story_spec,
AdCreativeFields::PRODUCT_SET_ID => $data['product_set_id'],
));
$creative->create();

Might be your issue is in creating AdCreativeVideoData.
search for line
AdCreativeVideoDataFields::IMAGE_URL => public_path().'/facebook/resize-image.jpg',
Here IMAGE_URL requires url path like http://example.com/myimage.jpg. You are giving directory path that might cause problem.
If your image is not directly accessible from URL then you should create IMAGE_HASH. For this see below.
try {
$image = new AdImage(null, $data['account_id']);
$image->{AdImageFields::FILENAME} = public_path().'/facebook/resize-image.jpg';
$image->create();
// Image_hash = $image->hash
} catch (Exception $e) {
echo 'Error message: ' . $e->getMessage() . "\n" . "<br/>";
echo 'Error Code: ' . $e->getCode() . "<br/>";
}
And replace IMAGE_URL to IMAGE_HASH in your AdCreativeVideoData like this
$video_data = new AdCreativeVideoData();
$video_data->setData(array(
AdCreativeVideoDataFields::IMAGE_HASH => $image->hash,
AdCreativeVideoDataFields::VIDEO_ID => $video->id,
AdCreativeVideoDataFields::CALL_TO_ACTION => array(
'type' => AdCreativeCallToActionTypeValues::LIKE_PAGE,
'value' => array(
'page' => $data['page_id'],
),
),
));
