Hello. When I generated the code I found php artisan route:list complains. Can anyone help on this issue? Thanks.

Hi, thx for reporting - at 1st glance it seems like a Laravel's problem from here:

namespace Illuminate\Routing;
class Route
{
    public function __construct($methods, $uri, $action)
    {
        $this->uri = $uri;
        $this->methods = (array) $methods;
        $this->action = $this->parseAction($action);

        if (in_array('GET', $this->methods) && ! in_array('HEAD', $this->methods)) {
            $this->methods[] = 'HEAD';
        }

        $this->prefix($this->action['prefix'] ?? '');
    }

As it turns out that Reflection can't recognise the actual type of constructors parameter $method in this case and it is normal because there is no type-hint. But we can't provide a type as it can be an array as well as string.
I will investigate this problem further if U find the solution faster, please let me know.
PHP 7.4.3/Laravel 7.0.8

Facing the same issue, any solutions for this?

P.s: I still don't understand why you would abandon this package cause honestly, as far as json:api is concerned, I find no better alternatives out there. Laravel-JSON-API might be a worthy competitor but hell no would I write documentation manually when it can be generated
