Can you please try with 4.2.2 to make sure this hasn't already been fixed

 buff_func.callv([null, -1, null])

You are calling a one argument function with three arguments. I couldn't reproduce the bug with the provided snippet, please add more details.

func create_function(tokens: Array[String]):
    var buff_func = func do_stuff(entity: Object) -> void:
        prints(tokens, entity)
    buff_func.callv([null, -1, null])

func _ready() -> void:
    create_function([""])

By the way, the error is not displayed with callv, only with call (i.e. buff_func.call(null, -1, null)):

Sorry about that. I went and created a new project with this bug. The project produces the bug locally

Tried it with 4.2.2, same result.
