An exception has been thrown during the rendering of a template ("Twig\Extension\CoreExtension::constant(): Return value must be of type string, App\Enum\TransactionFinType returned").

Twig\Error\RuntimeError:
An exception has been thrown during the rendering of a template ("Twig\Extension\CoreExtension::constant(): Return value must be of type string, App\Enum\TransactionFinType returned").

{{ constant('App\\Enum\\TransactionFinType::FIN_TYPE_RESULT').value }}

After upgrade Twig from 3.9 to 3.10

This is due to #4063 which changed the constant method prototype:

public static function constant($constant, $object = null): string

Constants may also return most of the scalar types, arrays, native enums etc.

See #4085
