Issue With DraftOrderComplete Grapql API

I’m developing a custom app for our website. This app’s features include:

  • Create a Shopify draft order
  • Complete the Draft order created.

It work well previously.

But From 26-Oct-2022, when I call Shopify graph API to complete the order. Sometimes, It returns the error message:

{
    "draftOrderComplete": {
        "draftOrder": null,
        "userErrors": [
            {
                "field": null,
                "message": "Resulting order was not persisted"
            }
        ]
    }
}

Can anyone please give me advice about this error? It looks like nothing is wrong with our app.

Did you ever figure this out? This just started happening to me.
