Hello, I have following code, which forwards Set-Cookie headers from one of the proxied Graphql APIs - but it occasionally returns following error

uWS.HttpResponse must not be accessed after uWS.HttpResponse.onAborted callback, or after a successful response. See documentation for uWS.HttpResponse and consult the user manual.

import { MeshContext } from '../../.mesh';
import { MeshPlugin } from '@graphql-mesh/types'
import { HttpResponse } from "uWebSockets.js";

const useAddAuthHeaderPlugin = (): MeshPlugin<MeshContext> => {
  return {
    onFetch(payload) {
      /** @ts-ignore WHY TYPE DOESNT CONTAIN RES ? */
      const response: HttpResponse = payload.context?.res;

      if (!response) {
        return;
      }

      let aborted = false

      response.onAborted(() => {
        aborted = true
      })

      return async (payload) => {
        /** @ts-ignore cookies comes in single string, parsing is nearly impossible. doesnt expose any other method */
        const setCookie: string[] | undefined = payload.response.headers.headersInit['set-cookie']
        if (!setCookie) {
          return
        }

        if (!aborted) {
          response.cork(() => {
            setCookie.forEach((cookie) => response.writeHeader('Set-Cookie', cookie))
          });
        }
      }
    }
  }
}

export default useAddAuthHeaderPlugin;

Any ideas why this could be happening?

It is not recommended to access the internal response object directly. You can use whatwg-node's cookies plugin for cookie management;

Thanks! Seems to be working now, tho cookies needs to be parsed.
