At the moment its not possible to get from an inventory shipment back to the inventory transfer, even though the relationship exists the other way around (from transfer down to shipments).
It would be really helpful to traverse the relationship this way inventoryShipment - GraphQL Admin
Yeah, this makes logical sense to me and you’re right this is currently a limitation. Just to confirm, would this be in cases where a fulfillment provider, for example, has to revert a shipment that’s already in process and put it back into a “transfer” queue? Just trying to understand the shape of the problem this would solve.
