Waiting Room Resys

Hello, I have a big problem.
I am using the basic waiting room that is included with the business plan, which I recognize is very effective.
When I activate the waiting room, it blocks the bank’s responses (redsys).
When the waiting room is not activated, the bank configuration works correctly, since the corresponding rules are applied so that it is not blocked.
If I try to make an omission rule in the waiting room, so that the bank’s response is effective, it does not allow me, indicating an error 1034. Can someone help me solve this?
Thank you all
