I'm using the Inventory API's bulkCreateOffers to make new offers. However, every single call leads to error 2003 and I'm wondering if there's anything I'm doing wrong. The requests look fine to me and all referenced entities exist.
Any help would be greatly appreciated!
Here's the latest request&response (in order to create a minimal test case, I'm only creating a single offer with a simplfied description at the moment, but the error appears even when there's more):
