Additional context
The solution is probably to implement the missing method in the adfs-module. If analysis supports this, this issue should be moved to the proper repository.

从 modules/admin/src/Controller/Federation.php:273 开始，这里 getHostedIdP 调用了 ADFS 类中缺失的 getHostedMetadata 方法。检查已安装的 adfs-module 实现及其元数据处理，然后使用报告的环境复现 module.php/admin/federation；当页面加载时不再出现 undefined-method exception 时即表示完成。
