Example Plugin (SwagPluginSystem) causes White Screen for Shopware 5.7

[BenRoe]

I download the zip file from the https://github.com/shopware/devdocs/blob/master/source/developers-guide/example-plugin/index.md and put the SwagPluginSystem folder in custom/plugins. After activating the plugin in the Plugin-Manager, i get a white screen on the shop page.

hey @BenRoe

thanks for bringing this up, but I cannot reproduce this. Do you have some error message? Please have a look here https://docs.shopware.com/en/shopware-5-en/tutorials-and-faq/debugging-error-messages-in-shopware#tweaks-for-the-config-php

I use Lando with the LAMP receipt and Shopware 5.7 on OSX 10.15.7

Fatal error: Uncaught Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException:

hey @BenRoe this is a known issue and will be fixed to the final 5.7 release, where the subscriber will be set to public by default
