Fatal error creating coupon programmatically

When creating a coupon programmatically i get this error:

[18-Feb-2023 17:54:37 UTC] PHP Fatal error:  Uncaught TypeError: Argument 1 passed to Automattic\WooCommerce\GoogleListingsAndAds\Coupon\SyncerHooks::Automattic\WooCommerce\GoogleListingsAndAds\Coupon\{closure}() must be of the type int, object given, called in /home/XXXXX/public_html/wp-includes/class-wp-hook.php on line 308 and defined in /home/XXXXX/public_html/wp-content/plugins/google-listings-and-ads/src/Coupon/SyncerHooks.php:107

Coupon is created with the following code:

	$coupon = new WC_Coupon();
	$coupon->set_code( 'ABC-123' );
	$coupon->set_description( 'My coupon description' );
	$coupon->set_discount_type( 'percent' );
	$coupon->set_amount( 10 );
	$coupon->set_individual_use( true );
	$coupon->set_usage_limit( 1 );
	$coupon->set_usage_limit_per_user( 1 );
	$coupon->set_limit_usage_to_x_items( 0 );
	$coupon->set_free_shipping( false );
	$coupon->set_email_restrictions( '[email protected]' );
	$coupon->set_date_expires( '2023-12-31' );
	$coupon->set_minimum_amount( 100 );
	$coupon->save();

I was using this with no problems until i installed GoogleListingsAndAds. Disabing the plugin allows my function to execute and the coupon to be created.

Any thoughts?

[EDIT]
I’m doing this in a script outside the normal WP structure, and including “wp-blog-header.php”, “wp-config.php”, and “wp-load.php” in the begining of that script. Using similar code in my FUNCTIONS.PHP file i get no errors. What am i missing?!
