Issues with App Store listing

I’m having an issue when browsing the App Store pages on my instance where it renders all the categories but then any category that I pick shows no apps. I’m running v13.0.0.3 (alpha) for testing and have verified the apps.json and categories.json files are populated correctly on the data directory.

Debugging through the code I notice that when the route (AppSettings#listApps) invokes : AppSettingsController's public function listApps($category = ''), the category parameter is empty even though I see it being passed in the URL: http://localhost:8080/index.php/settings/apps?category=auth

Any idea why the router would be discarding the parameter or that wouldn’t be making to the controller?

I figured out what my problem was. In my config I had the htaccess.RewriteBase config key set to / so I wouldn’t see the index.php on the URLs, alongside the other relevant configs, and apparently the rewrite rule it generates doesn’t include the QSA flag, so I had to change that in Setup.php:

		$rewriteBase = $config->getValue('htaccess.RewriteBase', '');
		if($rewriteBase !== '') {
			$content .= "\n<IfModule mod_rewrite.c>";
			$content .= "\n  Options -MultiViews";
			$content .= "\n  RewriteRule ^core/js/oc.js$ index.php [PT,E=PATH_INFO:$1]";
			$content .= "\n  RewriteRule ^core/preview.png$ index.php [PT,E=PATH_INFO:$1]";
			$content .= "\n  RewriteCond %{REQUEST_FILENAME} !\\.(css|js|svg|gif|png|html|ttf|woff|ico|jpg|jpeg)$";
			$content .= "\n  RewriteCond %{REQUEST_FILENAME} !core/img/favicon.ico$";
			$content .= "\n  RewriteCond %{REQUEST_FILENAME} !core/img/manifest.json$";
			$content .= "\n  RewriteCond %{REQUEST_FILENAME} !/remote.php";
			$content .= "\n  RewriteCond %{REQUEST_FILENAME} !/public.php";
			$content .= "\n  RewriteCond %{REQUEST_FILENAME} !/cron.php";
			$content .= "\n  RewriteCond %{REQUEST_FILENAME} !/core/ajax/update.php";
			$content .= "\n  RewriteCond %{REQUEST_FILENAME} !/status.php";
			$content .= "\n  RewriteCond %{REQUEST_FILENAME} !/ocs/v1.php";
			$content .= "\n  RewriteCond %{REQUEST_FILENAME} !/ocs/v2.php";
			$content .= "\n  RewriteCond %{REQUEST_FILENAME} !/robots.txt";
			$content .= "\n  RewriteCond %{REQUEST_FILENAME} !/updater/";
			$content .= "\n  RewriteCond %{REQUEST_FILENAME} !/ocs-provider/";
			$content .= "\n  RewriteCond %{REQUEST_URI} !^/.well-known/acme-challenge/.*";
			$content .= "\n  RewriteRule . index.php [QSA,PT,E=PATH_INFO:$1]";
			$content .= "\n  RewriteBase " . $rewriteBase;
			$content .= "\n  <IfModule mod_env.c>";
			$content .= "\n    SetEnv front_controller_active true";
			$content .= "\n    <IfModule mod_dir.c>";
			$content .= "\n      DirectorySlash off";
			$content .= "\n    </IfModule>";
			$content .= "\n  </IfModule>";
			$content .= "\n</IfModule>";
		}
