In the whereIn method of the model, if the input value is set to null, an error occurs in the count function inside the method. Please either enforce a data type for the value parameter in the method's input and resolve the mentioned bug.

1. Create a Laravel model and use the whereIn method.
2. Pass null as the value for the whereIn method.
3. Run the code.

Expected Result:
The method should handle the null value gracefully or throw a meaningful exception.

Actual Result:
An error occurs in the count function inside the whereIn method.

Please either enforce a data type for the value parameter in the method's input and resolve the mentioned bug.

The type hint for $values is mixed which includes null, it is set so to accept anything that is possible e.g. sub query. Therefore, data type should not change here.

We could maybe add a null check to the start of the fn:

if (is_null($values)) {
    throw new InvalidArgumentException('In Values cannot be Null');
}

but tbh, i expect such data check to happen before calling the whereIn anyways :>
