What do you exactly mean “you can call this function in the editor”? From where, how, with what parameter? Also what do you mean when you say you “cannot call the function with long parameter in the editor”? What’s the problem and what are you trying to do?
I mean if I have an int value in a function and a unity event in the editor, then I will see this function in the list of available functions. If I have a long value then function is inaccessible.
