How do i return the updated product in custom mutation

[sajjadh47]

`register_graphql_mutation( 'addUpdateLikedProduct', [

# inputFields expects an array of Fields to be used for inputting values to the mutation
'inputFields'         => [
	'id'	=> [
		'type'	=> [
			'non_null' => 'Int',
		],
	],
	'user_id'	=> [
		'type'	=> "Int",
	]
],

# outputFields expects an array of fields that can be asked for in response to the mutation
# the resolve function is optional, but can be useful if the mutateAndPayload doesn't return an array
# with the same key(s) as the outputFields
'outputFields'        => [
	'id'	=> [
		'type'	=> "Int",
		'resolve' => function( $payload, $args, $context, $info ) {
			return isset( $payload['product_id'] ) ? $payload['product_id'] : null;
		}
	],
	'product'	=> [
		'type'	=> "Product",
		'resolve' => function( $payload, $args, $context, $info ) {
			
			$resolver = new Product_Connection_Resolver( $payload, $args, $context, $info );

			$resolver->set_query_arg( 'post__in', [6075] ); // 6075 is for test only

			return $resolver->get_connection();
		}
	]
],

# mutateAndGetPayload expects a function, and the function gets passed the $input, $context, and $info
# the function should return enough info for the outputFields to resolve with
'mutateAndGetPayload' => function( $args, $context, $info ) {

	$response['product_id'] = $product_id;

	return $response;
}

] );`

above is my custom mutation to add/remove like from a product.. and after it's done i want to return the product object but that's not working this way... it returns The \"\" product type is not supported by the core WPGraphQL WooCommerce (WooGraphQL) schema.

what am i doing wrong or what is the process?
