Argument Error - Argument 1 passed to Symfony\\Component\\Workflow\\Marking::__construct() must be of the type array, string given

I am getting the following error

Argument 1 passed to Symfony\Component\Workflow\Marking::__construct() must be of the type array, string given, called in vendor/symfony/workflow/MarkingStore/MultipleStateMarkingStore.php on line 47

Hi Can you please provide sample code?

[Kreateyou]

Seem the error is thrown when i use any WorkflowTrai method workflow_can(),workflow_apply()

$model = Post::find(1);

$model->workflow_apply($request->get("workflow"));

$model->save();

Where request workflow is "to_review"

Can you please add:

• Your PHP version
• Your Laravel Version

I'm not able to reproduce this, and it will help a lot for debugging.

@Kreateyou and @brexis

in workflow.php (config)

'marking_store' => [
            'type' => 'single_state', // 'multiple_state',
            'arguments' => ['status'],
        ],

fixed my issue, but you need to fix this issue :)

Hello, I had the same error message with the multiple_state type (not with single_state) To solve it with the multiple_state, you have to specify the field of your argument in your model like this :

protected $casts = [
    'status' => 'array'
];
