When i use annotation to map argument as "Non-nullable array of non-nullable values" the scheme is built correctly. But i got error during query execution:

GraphQL\Error\InvariantViolation: Type loader is expected to return type "Int!", but it returned ""[0]

Example of mapping:

/**
 * @GQL\Query(type="[Order]", name="order",
 *     args={
 *         @GQL\Arg(name="orderIds", type="[Int!]!"),
 *     }
 * )
 */
public function getOrders(array $orderIds): Promise
{
    ...
}

@Vincz should we also patch from 0.12 ?

Hey @mcg-web :-) Yes, you can. It fixes the Arguments Transformer without any BC.

Thanks @Vincz for your answer, we should patch from the lower maintained version branch where the bug was introduce (0.12 in this case). We always merge branches from the older version to the newest (0.11 -> 0.12 -> 0.13 -> ... -> master). so patch will be automatically apply to other newest versions using this flow. I'll add a note about this in contributing file.
