Using urql/core as NodeJS standalone client

[snaplesec]

I'm trying to execute a mutation in a Node application, but doesn't seem to return anything, and it isn't working, but also throws no errors.
Not sure what is missing with it.

import client from './lib/gqlClient'
import { gql } from '@urql/core'

const ADDATTACH = gql`
mutation AddAttachments($attach: [ClaimAttachment]!){
  claimAttachments(attachments: $attach) {
    fnolId
  }
}`

export async function putAttachments(att) {
    const atts = att
    // @ts-ignore
    const res = await client.executeMutation(ADDATTACH, { attach: atts })
    console.log({...res})
    return res
}

executeMutation will return a stream which I don't think is what you're looking for, alternatively if you want to use promisified stuff you can use client.mutate

const res = await (client.mutation(ADDATTACH, { attach: atts }).toPromise())

EDIT: client.mutate --> client.mutation

Should be here

EDIT: apologies it's .mutation

Oh ok, let me change it.

How do I define fetch in node setup of urql?
I got the error about fetch not defined.

(node:28648) UnhandledPromiseRejectionWarning: ReferenceError: fetch is not defined
    at executeFetch (C:\Users\SteveNaples\OWL\insuredportal-upload-server\node_modules\@urql\core\src\internal\fetchSource.ts:30:13)

By defining fetch when you create the client or using a polyfill https://formidable.com/open-source/urql/docs/api/core/#client
