hey all … i am dealing with a typing error that i really don’t understand why its happening … i have tried to change the typing and also remove default values but no matter what i do … i always get the same error … anyone have any ideas

```
TypingError: Failed in nopython mode pipeline (step: nopython frontend)
Cannot unify PriceTuple(float64 x 5) and PriceTuple(float64, array(float64, 1d, F), array(float64, 1d, F), array(float64, 1d, F), array(float64, 1d, F)) for 'prices.4', defined at e:\coding\backtesters\quantfreedom\quantfreedom\nb\simulate.py (191)

class PriceTuple(NamedTuple):
# PossibleArray = Union[np.ndarray, int, float, bool]

Here is some info from the debugger

```
prices := PriceTuple(float64, array(float64, 1d, F), array(float64, 1d, F), array(float64, 1d, F), array(float64, 1d, F)),
prices.1 := PriceTuple(float64, array(float64, 1d, F), array(float64, 1d, F), array(float64, 1d, F), array(float64, 1d, F)),
prices.2 := PriceTuple(float64 x 5),
prices.3 := PriceTuple(float64 x 5),
prices.4 := PriceTuple(float64 x 5),
```
