This application has no configured error view, so you are seeing this as a fallback

这个错误信息是由于应用程序没有配置错误视图而导致的。这意味着当应用程序遇到错误时，它无法显示一个友好的错误页面。通常，这种情况下，应用程序会返回一个 HTTP 状态码和一些错误信息，但是没有更多的信息来帮助用户解决问题。

为了解决这个问题，你需要配置一个错误视图，以便在应用程序遇到错误时，能够显示一个友好的错误页面。这个页面应该包含一些有用的信息，例如错误代码、错误消息和可能的解决方案。

引用和中提到了"This application has no configured error view, so you are seeing this as a fallback."这个错误提示。这个错误提示意味着应用程序没有配置错误视图，所以你看到了这个默认的回退页面。这通常发生在应用程序无法找到所请求的页面的情况下，比如在请求一个不存在的页面时会出现404错误。引用中也提到了这个错误提示，说明在预约挂号系统的前端遇到了一个小bug，最后发现是用户登录模块没有注册导致的。所以这个错误提示通常表示应用程序在处理请求时发生了错误，并且没有相应的错误视图来显示给用户。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

This application has no explicit mapping for /error, so you are seeing this as a fallback.

This error message typically appears when a user tries to visit a URL that does not exist or has not been properly configured in the application. The message indicates that the application is unable to find an appropriate page to display for the requested URL, and instead displays a default error message.

To resolve this issue, you should review the application's configuration and ensure that all URLs are properly mapped to the appropriate pages. You may also want to check the application's logs for any additional information on the error, which can help you identify the root cause and develop a solution.
