PATCH 405 (Method Not Allowed) Groovy - rest

Question

I'm trying to do a HTTP operation with PATCH method toward a Groovy Script. If I do that request with Postman Interface I obtain a 200 ok but when I do with the Groovy Script I obtain a 405 Error Code.
Postman Request:
Postman Request
That request is did for a Groovy with JSON Data.
The function that process the request is the next:
public Object sendHttpRequest(String url, String operation, String jsdonData,
String user, String password) throws Exception {
println("Start sendHttpRequest() method");
Object gesdenResponse = null;
HttpURLConnection conn = null;
try {
println("Opening HTTP connection...");
println("URL: " + url);
URL obj = new URL(url);
conn = (HttpURLConnection) obj.openConnection();
conn.setRequestProperty("Authorization", String.format("Basic %s", getProtectedCredentials(user, password)));
println("Header \"Authorization: *****\" set up");
String method = null;
switch (operation) {
case "PASSWORD":
method = 'PATCH';
println("PASSWORD Operation");
break;
default:
break;
}
if (method?.equals("PUT") || method?.equals("POST") ||method?.equals("PATCH")) (conn.setDoOutput(true));
if (method == "PATCH") {
println("MODIFICAMOS CABECERA PARA PATCH ");
conn.setRequestProperty("X-HTTP-Method-Override", "PATCH");
conn.setRequestMethod("POST");
} else {
conn.setRequestMethod(method);
}
println("Setting up custom HTTP headers...");
conn.setRequestProperty(GesdenConstants.HTTP_CUSTOM_HEADER_SYSTEM_KEY, GesdenConstants.HTTP_CUSTOM_HEADER_SYSTEM_VALUE);
println(String.format("Custom header \"%s: %s\" set up", GesdenConstants.HTTP_CUSTOM_HEADER_SYSTEM_KEY, GesdenConstants.HTTP_CUSTOM_HEADER_SYSTEM_VALUE));
conn.setRequestProperty(GesdenConstants.HTTP_CUSTOM_HEADER_ACCEPT_KEY, GesdenConstants.HTTP_CUSTOM_HEADER_ACCEPT_VALUE);
println(String.format("Custom header \"%s: %s\" set up", GesdenConstants.HTTP_CUSTOM_HEADER_ACCEPT_KEY, GesdenConstants.HTTP_CUSTOM_HEADER_ACCEPT_VALUE));
conn.setRequestProperty(GesdenConstants.HTTP_CUSTOM_HEADER_CONTENT_TYPE_KEY, GesdenConstants.HTTP_CUSTOM_HEADER_CONTENT_TYPE_VALUE);
println(String.format("Custom header \"%s: %s\" set up", GesdenConstants.HTTP_CUSTOM_HEADER_CONTENT_TYPE_KEY, GesdenConstants.HTTP_CUSTOM_HEADER_CONTENT_TYPE_VALUE));
if (jsdonData != null && !jsdonData.isEmpty()) {
conn.setRequestProperty("Content-Length", String.format("%s", Integer.toString(jsdonData.getBytes().length)));
conn.getOutputStream().write(jsdonData.getBytes("UTF-8"));
println(String.format("JSON data set up" + conn));
}
println("Waiting for server response...");
println(String.format("conn es "+conn));
BufferedReader input = new BufferedReader(
new InputStreamReader(conn.getInputStream()));
String inputLine;
StringBuffer data = new StringBuffer();
println(String.format("linea " +inputLine));
while ((inputLine = input.readLine()) != null)
{
data.append(inputLine);
println(String.format("linea " +inputLine));
}
} catch (Exception e) {
throw e;
} finally {
if (conn != null) {
conn.disconnect();
println("HTTP connection closed");
}
println("Finish sendHttpRequest() method");
}
return gesdenResponse;
}
The log of the code is the next:
