How to redirect a websocket $connect on Serverless

Hey guys :raising_hand_man:, my first topic here - so please bear with me…

We are building an API PROXY to centralize all services under the same domain and API GW.

I need to redirect a websocket $connect event to a legacy address

Lambda redirects with 301 and sends Location header

exports.wsHandler = async (event, _context, _calllback) => {
  // Redirect URL
  return {
  	statusCode: 301,
  	headers: { 
  		Location: 'wss://',

Problem again…
No cors on API GW Websockets so I can tell it to accept Location header

Anyway I can explicit my API GW to accept the headers?

Thanks in advance :blush:
