I get the error cannot access private member declared in class when trying to nativize a blueprint including the node Niagara Set Vector Array.
Engine version : 4.26.2

error C2248: ‘UNiagaraDataInterfaceArrayFunctionLibrary::SetNiagaraArrayVector’: cannot access private member declared in class ‘UNiagaraDataInterfaceArrayFunctionLibrary’

Was a solution ever found for this? I’m having the exact same issue and can’t find anything on how to solve.

You can put the node in a function library, then they don’t get nativized, and you can call the function containing the node from a nativized blueprint.
I forgot to post the bug report, but I don’t know if they still fix nativization stuff, as it looks like it’s not going to be in UE5.
