Resolved [org.springframework.web.HttpRequestMethodNotSupportedException: Request method 'GET' not supported]

This error occurs when a request is made with an HTTP method that is not supported by the server. The server expects a different HTTP method for the requested resource.

To resolve this error, you need to make sure that the HTTP method used in the request is supported by the server. Check the documentation or API of the server to see which HTTP methods are supported.

If you are using Spring Framework, you can use the @RequestMapping annotation to specify the supported HTTP methods for a particular endpoint. For example, if you want to support only POST requests for an endpoint, you can use the following code:

@RequestMapping(value = "/example", method = RequestMethod.POST)
public ResponseEntity<?> exampleEndpoint() {
  // your code here
}

Make sure that the method parameter in the @RequestMapping annotation matches the HTTP method used in the request.
