Unable Create Webhook in Java

Hello, I am trying to create webhook, but when i test always get error like this

{

"errors": [

    {

        "message": "The remote server which is intended to receive the webhook did not respond with the handshake secret.",

        "help": "For more information on API status codes and how to handle them, read the docs on errors: https://developers.asana.com/docs/errors"

    }

]

}

but in my ngrok logs I’ve done what the documentation says for response, any feedback?
Thanks

HTTP/1.1 200 
X-Hook-Secret: ecb0f15e2bbece5546fbcbaea98a1484
Content-Length: 0
Date: Wed, 23 Feb 2022 08:56:54 GMT

this is my response

import lombok.extern.slf4j.Slf4j;
import org.apache.logging.log4j.LogManager;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.*;

import java.util.Map;
import java.util.logging.Logger;

@RestController
@Slf4j
public class AsanaController {

@RequestMapping("/asana-webhook")
public ResponseEntity handle(@RequestHeader Map<String, String> headers,
                             @RequestBody String payload) {
    HttpHeaders responseHeaders = new HttpHeaders();
    responseHeaders.add("X-Hook-Secret", headers.get("x-hook-secret"));

    log.info(headers.get("x-hook-secret"));
    String xhook = "X-Hook-Secret: " + headers.get("x-hook-secret");

    return new ResponseEntity<>(responseHeaders, HttpStatus.OK);
}

}

and this is my code in java

public ResponseEntity handle(@RequestHeader Map<String, String> headers,
@RequestBody String payload) {
HttpHeaders responseHeaders = new HttpHeaders();
responseHeaders.set(“X-Hook-Secret”,
headers.get(“x-hook-secret”));

    return ResponseEntity.ok()
            .headers(responseHeaders)
            .body("X-Hook-Secret: "+ headers.get("x-hook-secret"));
}

change my code like this, and now thats ok
