Hi,
We have observed this a few times in the past week. We create a purchase order via GraphQL and the server hangs. For example, PO 2620 (our id, dashboard ID is 811628), was successfully created but the server response was 504.
We have confirmed that all of the lines are correct (so nothing obvious to us like having a product that doesn’t exist).
Can you take a look and let us know if this is something on our end or yours?
Thanks!
