Laravel 5.3 - Validation rule min and required_if issue

So in a Request we have some validation, where the type field will be review, which means the body field has to have a minimum of 6 characters.

public function rules(){
     return [
       'type' => 'required|in:star_rating,review',
       'body' => 'required_if:type,review|min:6'
     ];
 }

However, the issue is that when the type is star_rating, I get an error that The body must be at least 6 characters.

This should not happen, since the body is optional and ONLY should be required and validated with min:6 if type is review. I can't seem to figure out why it runs the min:6 validation on it even if the type is star_rating.

Any idea how to get it to work as intended?
