I created a Contract ref object. Now in my ContractController I want to list an array of contracts. How can I do it? I got this error Couldn't find constant array when trying to add type=array in OA\Items

/**
 * @OA\Info(title="Contract API", version="1")
 */

class ContractController extends Controller
{
    /**
     * @OA\Post(
     *     path="/api/v1/contract/list",
     *     tags={"contact"},
     *     summary="List Contract",
     *     operationId="list",
     *     @OA\Parameter(
     *         name="keyword",
     *         in="path",
     *         description="keyword to search contracts",
     *         required=false,
     *         @OA\Schema(
     *             type="string"
     *         )
     *     ),
     *     @OA\Parameter(

    public function list(Request $request)
    {
        $contracts = Contract::factory()->count(10)->make();
        return response()->json([
            'message' => 'good',
            'contracts' => $contracts
        ], 200);
    }
}

/**

 *     title="Contract model"
 * )
 */
class Contract extends Model
{
    use HasFactory;

    /**
     * The unique identifier of a product in our catalog.
     *
     * @var integer
     * @OA\Property(format="int64", example=1)

    public $id;

    /**
     * @var string
     * @OA\Property(format="string", example="contract 001")
     */
    public $contract_title;
}

Answer 1

Use type="array", (with "s) instead of type=array,

Answer 2

I know its late but Try to use

 *            @OA\MediaType(
 *                 mediaType="application/json",
 *                 @OA\Schema(
 *                 type="array",
 *                      @OA\Items(
 *                          ref="#/components/schemas/Contract"
 *                      ),
 *                 )
 *          )  

Insead of @OA\JsonContent
