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

Possible solution:
This error message is usually displayed when the Spring Boot application encounters an unexpected exception that is not handled by any of the defined error mapping routes. To fix this, you can define a custom error mapping route in your application's controller.
For example, you can create a controller method that maps to the "/error" endpoint and returns a custom error page or message. Here's an example:
```
@Controller
public class MyErrorController implements ErrorController {
@RequestMapping("/error")
public String handleError(HttpServletRequest request) {
// Get the error status code and message
Integer statusCode = (Integer) request.getAttribute("javax.servlet.error.status_code");
String message = (String) request.getAttribute("javax.servlet.error.message");
// Log the error message
log.error("Error {} - {}", statusCode, message);
// Return a custom error page or message
return "error";
}
@Override
public String getErrorPath() {
return "/error";
}
}
```
In this example, the "handleError" method maps to the "/error" endpoint and retrieves the error status code and message from the request attributes. It then logs the error message and returns a custom error page or message.
Note that the controller class also implements the "ErrorController" interface and overrides the "getErrorPath" method to return the "/error" endpoint. This is necessary to ensure that Spring Boot uses this controller for handling errors.
Once you have defined your custom error controller, you can customize the error page or message as needed.
