camel-restlet can't send an array of cookies at once for responce

I tried to send an array of cookies at once to the browser, but I'm getting this error:

java.io.IOException: Empty cookie name detected. Please check your cookies

But the same code without any changes works just fine with "jetty", "undertow","servlet" ...

Parth of the code that I used for sending multiple cookies:

public Order getOrder(@Headers Map headers, @ExchangeProperties Map properties,Exchange exchange){

List<String> cookieList = new ArrayList<>();
cookieList.add("Key7001=Value7001;Path=/;HttpOnly=true;session-token=test;Expires=Thu, 06-Jan-2022 00:00:00 GMT;");
cookieList.add("Key7002=Value7002;Path=/;HttpOnly=true;session-token=test;Expires=Thu, 06-Jan-2022 00:00:00 GMT;");

// Sets the two cookies on the browser

headers.put("Set-Cookie",cookieList); /// this will return an error saying java.io.IOException: Empty cookie name detected. Please check your cookies

//Set with one cookie on the browser works just fine

//headers.put("Set-Cookie","Key6001=Value6001;Path=/;HttpOnly=true;session-token=test;Expires=Thu, 06-Jan-2022 00:00:00 GMT;");

I uploaded the full code in github: https://github.com/odehghan/camelrestlet
