Hello,
How to debug the following error

Spryker\Glue\Kernel\ClassResolver\DependencyProvider\DependencyProviderNotFoundException - Exception: Spryker Kernel Exception
Can not resolve NgcategoryRestApiDependencyProvider for your module "NgcategoryRestApi"
You can fix this by adding the missing DependencyProvider to your module.

Alberto Reyer

Create a file named NgcategoryRestApiDependencyProvider in the top level of your module, that looks like:

<?php

namespace Pyz\Glue\NgcategoryRestApi;

use Spryker\Glue\Kernel\AbstractBundleDependencyProvider;
use Spryker\Glue\Kernel\Container;

/**
 * @method \Pyz\Glue\NgcategoryRestApi\NgcategoryRestApiConfig getConfig()
 */
class NgcategoryRestApiDependencyProvider extends AbstractBundleDependencyProvider
{
    /**
     * @param \Spryker\Glue\Kernel\Container $container
     *
     * @return \Spryker\Glue\Kernel\Container
     */
    public function provideDependencies(Container $container)
    {
        $container = parent::provideDependencies($container);

        return $container;
    }
}

Unknown

Your DependencyProvider must be at the root of your module
• NgcategoryRestApi folder
◦ NgcategoryRestApiDependencyProvider.php
◦ NgcategoryRestApiConfig.php

Thanks for replay,
I have already created the files withe the needful dependencies, I following category-rest-api module . Kindly provide more suggestions so that I can fix this.

Alberto Reyer

You named the Dependency Provider NgcategoriesRestApiDependencyProvider, but your module is named NgcategoryRestApi so the correct name for the dependency provider would be NgcategoryRestApiDependencyProvider .
You should stick to one name either singular or plural. Suggestion from Spryker is to stick with the plural form.

1. don't use bridges on Project level, they are a workaround in the core for the missing interface segregation principle but are not necessary in the project as strict segregation is not a matter in the project namespace.
2. Your issue is that addCategoryStorageClient does not return the container (doc block tells wrongly that it does), which is an issue the IDE already points out in line 41

Alberto Reyer

Note: the stack trace exactly tells you the error that NULL is passed into addStoreClient, please read your error messages carefully before you ask for help.
