I'm running bulk quantity updates using the Feed API LMS_REVISE_FIXED_PRICE_ITEM feed type.
I'm getting a small amount of failures for these records and the error messages that come back are very strange, for example:
Developer name invalid.
We're having trouble updating your listing right now.
Invalid IAF token.
these errors comes from a single batch of updates, how can the IAF token be invalid and developer name be invalid for one update but not the others in a single batch?
