"Failed to instantiate component or class" when calling Craft module

Question

I created a module with the pluginfactory generator. The module is used for generating a zip file with all the files belonging to a project.

In the composer.json file, I added the following:

"autoload": {
    "psr-4": {
      "zipassetscraft3module\\": "modules/zipassetscraft3module"
    }
  },

in the config/app.php I added:

'modules' => [
      'zip-assets-craft-3-module' => \modules\zipassetscraft3module\ZipAssetsCraft3Module::class,
    ],

In the file controllers/DefaultController.php I added a function called actionDownload() as well as a download() function in the file services/ZipAssetsCraft3ModuleService.php

On the website I have a form with the following url as action: https://default.com/actions/zip-assets-craft-3-module/default/download

When I submit the form, I get an error:

Invalid Configuration – yii\base\InvalidConfigException Failed to instantiate component or class "modules\zipassetscraft3module\ZipAssetsCraft3Module".

Caused by: ReflectionException Class modules\zipassetscraft3module\ZipAssetsCraft3Module does not exist

I have dumped the composer autoload, but I don't know why it's not working. Any ideas what I need to change to get this working?

This is the file structure of the module:

So the error message says, there is a class missing, in which file is this class looked for?

I came across the same issue. So how i solved it is to modify the modules array like this and now the module is loading:

return [
    'modules' => [
        'zip-assets-craft-3-module' => [
            'class' => \modules\zipassetscraft3module\ZipAssetsCraft3Module::class,
        ],
    ],
    'bootstrap' => ['zip-assets-craft-3-module'],
];
