Draft order invoice payment breaks code

Hi! Last week something stopped working on our draft order invoice payments. We create draft orders through the GraphQL API, selecting a handle for the shipping rate. We used to get the correct code at the shipping line when the customer paid the invoice. Since last Wednesday, we receive a shipping line with code custom and origin shopify. We have not changed anything, and marking the draft order as paid from admin gives us the correct code. Did something change that could have broken payments on draft order invoices?

Hey @DRS, can you share the details of your mutation including the API version? I would like to see if I can replicate this as well.

It has been fixed. Thanks
