Commenting from your other post, if this is your specific problem, you need to input the variables you want to return like so:

query MyQuery($filter: ProductFilter) {
	queryProduct(filter: $filter) {
		id
		name
		quantity
		availability
		price
		image_src
		category
		brand
		specification
		description_shot
		description_long
	}
}

Otherwise, as @amaster507 said, we need more information on your exact problem with error messages, expected results, etc…
