Use numba dtype with jitclass

Numba Support: How do I do ...?

I am having trouble initialising a jitclass with a singular instance of numpy dtype. The following is the code where I am getting the error.
import numpy as np
from numba import jitclass, typeof

counter_dtype = np.dtype([('element', np.int32, 5)])
one_counter = np.zeros(1, dtype=counter_dtype)[0]

spec = [
    ("counter", typeof(one_counter))
]

@jitclass(spec)
class UpdatingStuff: 
    def __init__(self, counter):
        self.counter = counter

UpdatingStuff(one_counter)
