问题描述

我对新系统也有同样的问题，这是一个非常古老的错误。注册失败。 https://github.com/2sic/app-events-and-courses/issues/1 我正在寻找解决方法。

Read this blog - it tells you what changed and how to fix it: https://2sxc.org/en/blog/post/fixing-the-breaking-change-in-2sxc-9-8-list-instead-of-dictionary

Since you installed a new system (that's what I understand), could you point me to where you got the code - so I can have the original fixed?
