Target Enum Type is not instantiable

Question

I want to call a route which binds to parameter from the route which the enums have the enum type with a value of integer. However, after calling it I get error 500 with this error message Target [App\\Enums\\SportField] is not instantiable. with the exception of "exception": "Illuminate\\Contracts\\Container\\BindingResolutionException",. My enum files are like this

<?php
namespace App\Enums;
enum SportField:int {
case Football=1;
case Volleyball=2;
case BasketBall=3;
case Badminton=4;
}
enum SportSubField:int
{
case Normal=1;
case Double=2;
}

and the route and the action of this route:

//Route
Route::get('{field}/{subField}',[SingleController::class,'Get']);
//Action
public function Get(SportField $field,SportSubField $subField){
     return $field;
    }
}

the full message of the exception is

            "line": 21,
            "function": "require_once"
        }
    ]
}

I want to call the route and get the result without the Target [App\\Enums\\SportField] is not instantiable. exception message.

Laravel only allows string backed enums.

Using an implicit binding relies on the route section to match with Laravel's naming convention.

In your example, changing {field}/{subField} to {field}/{sportSubField} should work

// Route
Route::get('{field}/{sportSubField}',[SingleController::class,'Get']);

// Action
public function Get(SportField $field, SportSubField $subField) {
   return $field;
}

See the docs for a good example on Implicit Enum Binding

Having the same issue. I have bypassed the issue as below.

public function Get(int $field, int $subField)
{
    $fieldEnum    = SportField::from($field);
    $subFieldEnum = SportSubField::from($subField);

    return $field;
}

But i think there is better way to fix this issue.
