How to implement map bounds for RTS Camera?

For testing it out, I’ve already used BlockAll for collision on the capsule component as well as the blocking volume. I will try with only the invisible wall channel, but I do not understand why blockall fails to work. If I set it to overlap, I can see that it’s interacting because it print out a string. But nothing happens for Block. Is it some internal setting issue with pawn blueprints?
