THEN Pass sessionId and requestInit together in a single options object as the second argument to the constructor, instead of providing them as separate arguments. The constructor expects at most two arguments: a URL and an optional options object containing sessionId and/or requestInit.

const transport = new StreamableHTTPClientTransport(
  new URL(serverUrl),
  {
    sessionId: sessionId,
    requestInit: {
      headers: {
        "Authorization": "Bearer " + token,
      }
    }
  }
);
