Hello, I am using v3 api. I have an pipeline - contact creation/update (using contact/sync) with subsequent subscription to list (contactLists). And around once per 10-20 operations I see error - contact is created with 201 and subsequent subscription attempt fails with code 422 and body:
{“errors”:[{“title”:“The related contact does not exist.”,“detail”:“”,“code”:“related_missing”,“error”:“contact_not_exist”,“source”:{“pointer”:“/data/attributes/contact”}}]}
However, contact exists. Requests respect rate limit. How this could be solved or avoided? What could be the cause of this?
