Shopify APP 500 Internal Server Error with only Collaborator access!!!

20 0 3

Hi, Shopify wizards!

I'm currently having very weird issue. I built a Shopify app with React + Node.js. 

The app works fine unless I access it as a collaborator account. 

If I try to access(install or open), it shows 500 internal server error. I'm running the app with PM2, so I can see the error instantly with "pm2 monit"

This is the error I have.

This looks like obviously apollo or graphql error. But the weird thing is if I try with merchant account, all good. 

So I thought it might be related to apollo client version problem. I used apollo-boost library. So I upgraded it into @Apollo/client v 3.0 - the latest version. And updated all dependencies and codes although there were not much codes related to it. 

But the issue still persists. 

I checked to see on what part the issue was happening. 

The issue is in `get-subscription-url.js`  The following code is part of the file.


export const getSubscriptionUrl = async (ctx, shop) => {
  console.log("GETTING URL");
  const { client } = ctx;
  const appSubscriptionCreate = await client
      mutation: RECURRING_CREATE(process.env.HOST)
    .then(response => {
        "NEW URL: ",
    console.log("step 2-1 passed ");


I exactly see "GETTING URL" log, but I don't see "NEW URL: xxxx" log. 

I'm sharing RECURRING_CREATE function as well. 


export function RECURRING_CREATE(url) {
  return gql`
    mutation {
          name: "Standard Plan"
          returnUrl: "${url}"
          test: ${dev ? true : false}
          lineItems: [
            plan: {
              appRecurringPricingDetails: {
                  price: { amount: 9.99, currencyCode: USD }
        ) {
            userErrors {
            appSubscription {



And this is how I import `gql` from the updated @Apollo/client


import { gql } from "@apollo/client";


I tried bunch of researches, but haven't got any solutions yet. 

So my concern is...

1. This might be a reason of wrong code?

2. Should I reach to Shopify Staff with this issue?

3. But how come merchant account could work properly, but only Collaborator account? FYI, the collaborator account is `FULL PERMISSION`

4. I'm currently using an old API version. Something like this.. `https://${shop}/admin/api/2019-10/graphql.json`. The old API version might be the reason of this issue? 


I'm sharing some relevant posts from others here.


Some people said me it might be because of Shopify's Internal issue, and try to reload it again. But this issue always happens. 

Hope to a complete solution now.

Thank you in advance.
