If you were using
UProperty*
for wildcard property passing in Blueprint, the transition that worked for me was
TFieldPath<FProperty>
e.g.
UFUNCTION(BlueprintCallable, CustomThunk, meta = (CustomStructureParam = "AnyStruct"))
static bool ReadAnyStruct(TFieldPath<FProperty> AnyStruct);
Also in my case, stepping through a custom thunk,
ExactCast
became
CastField
e.g.
FStructProperty* StructProp = CastField<FStructProperty>(Stack.MostRecentProperty);
