Laravel 8 package development - Route Target class does not exist - php

Question

I know the title topic sounds similar to other questions, but I've searched many topics on stackoverflow and none resolve my issue.
I am currently developing a package under Laravel ^8.12, below the content of the function that register my routes:
protected function registerRoutes(): void
{
Route::prefix('workflowmakr')
->namespace('AlvariumDigital\WorkflowMakr\Http\Controllers')
->as('workflowmakr.')
->middleware(config('workflowmakr.routes_middleware'))
->group(__DIR__ . '/../routes/api.php');
}
And below is the content of the routes/api.php file:
<?php
use Illuminate\Support\Facades\Route;
Route::resource('actions', 'ActionController')->except(['created', 'edit']);
Route::resource('scenarios', 'ScenarioController')->except(['created', 'edit']);
Route::resource('statuses', 'StatusController')->except(['created', 'edit']);
Route::resource('transitions', 'TransitionController')->except(['created', 'edit']);
For a better view of the project architecture, below is a screenshot of the packages folder containing the package under development:
And finally, below is the composer.json declaring my package:
...
"extra": {
"laravel": {
"providers": [
"AlvariumDigital\\WorkflowMakr\\WorkflowMakrServiceProvider"
]
}
},
"autoload": {
"psr-4": {
"App\\": "app/",
"Database\\Factories\\": "database/factories/",
"Database\\Seeders\\": "database/seeders/",
"AlvariumDigital\\WorkflowMakr\\": "packages/AlvariumDigital/WorkflowMakr/src/"
}
},
...
When I execute the command php artisan route:list to view all my routes I got this error :
$> php artisan route:list
Illuminate\Contracts\Container\BindingResolutionException
Target class [AlvariumDigital\WorkflowMakr\Http\Controllers\ActionController] does not exist.

EDIT
Below is the content of the ActionController file:
<?php

use AlvariumDigital\Models\Action;
use AlvariumDigital\WorkflowMakr\Helpers\Constants;
use Illuminate\Routing\Controller;

use Illuminate\Support\Facades\Validator;
class ActionController extends Controller
{
/**
* Display a listing of the resource.
*
* #return \Illuminate\Http\JsonResponse
*/
public function index()
{
$query = Action::query();
if (config('workflowmakr.pagination_size') == -1) {
return response()->json($query->get(), 200);
}
return response()->json($query->paginate(config('workflowmakr.pagination_size')), 200);
}
// ...
}
EDIT 2
The content of the package composer.json file:
{
"name": "AlvariumDigital/WorkflowMakr",
"description": "Generalize the management of your workflows",
"type": "library",
"license": "MIT",
"authors": [

"role": "Developer"

],

}
Did I do something wrong or incomplete?
You can ask for more details if needed.

Answer 1

You have structured this directory incorrectly. You have the PSR4 autoloading loading the src directory as the namespace. Your controllers are not in the src folder, only the Service Provider is in there. So to composer there are no files for it to find and autoload based on your PSR4 autoloading.
