Override POOrderEntry ReleaseFromHold

I’m attempting to override the ReleaseFromHold action on the POOrderEntry graph, I need to add my own validation before the baseMethod is called.

I created the delegate using the following code, but I receive the error message below.

I’ve been able to override other action on this same graph using this method, is there something unique about the ReleaseFromHold action?

        public delegate IEnumerable ReleaseFromHoldDelegate(PXAdapter adapter);
        [PXOverride]
        protected IEnumerable ReleaseFromHold(PXAdapter adapter, ReleaseFromHoldDelegate baseMethod)
        {
           return adapter.Get();
        }
