当管理员帐户启用了 2FA 时，为包含特殊字符的用户名授予管理员权限会失败

题外话：即使在第一个示例中授予管理员权限有效，但单击按钮时浏览器控制台中也会出现错误：

PUT https://{my-forum}/admin/users/4/grant_admin 403 (Forbidden)

我已经了解到这是预期的

`run_second_factor!` failing when trying to promote admin

The 403 error is normal and expected — the frontend app catches the 403 response and interprets it as “can’t grant admin because 2FA is required, let’s navigate to the 2FA page”. What is not normal is: Can you tell me where you’re seeing this error? Is it a popup in the frontend? Error in logs? As you mention, I cannot find this error message anywhere in the entire history of the codebase, so it’s very weird.
