Eloquent relationship two parent and child

I have three tables: 1. questionbank 2. questiontype 3. questions

I need to retrieve the json response :

[{"questiontitle":"OSCE","questionbank":"osce bank","questiontype":"osce type"}]

My Models are:

1. questionbank

   class Questionbank extends Model {

   protected $fillable = [];
   
   protected $table = "QuestionBank";
   
   protected $dates = [];
   protected $primaryKey = "QuestionBankID";
   
   protected $visible = ["QuestionBank"];
   
   public static $rules = [
       // Validation rules
   ];
   
   

   }

2. questiontype

   class questiontype extends Model {

   protected $fillable = [];
   
   protected $dates = [];
   
   protected $table = "QuestionType";
   
   protected $primarykey = "QuestionTypeID";
   
   protected $visible = ["QuestionType"];
   
   public static $rules = [
       // Validation rules
   ];
   
   // Relationships
   
   

   }

3. questions

   class Questions extends Model {

   protected $fillable = ["QuestionTitle"];
   
   protected $dates = [];
   
   protected $primaryKey = "QuestionID";
   protected $foreignKey = "QuestionBankID";
   
   public static $rules = [
       // Validation rules
   ];
   protected $visible = ["QuestionTitle","QuestionBank","QuestionType"];
   // Relationships
   
   

   public function QuestionBank() { return $this->hasManyThrough('App\QuestionBank', 'App\questiontype', 'QuestionBankID', 'QuestionTypeID', 'QuestionBankID', 'QuestionTypeID'); } }

i got the error:

Column not found: 1054 Unknown column 'QuestionType.QuestionBankID' in 'field list' (SQL: select `QuestionBank`.*, `QuestionType`.`QuestionBankID` from `QuestionBank` inner join `QuestionType` on `QuestionType`.`QuestionTypeID` = `QuestionBank`.`QuestionTypeID` where `QuestionType`.`QuestionBankID`
