Is anyone else experiencing ongoing failures using Amazon Buy Shipping for orders containing bundle SKUs in ShipStation?
We first reported this to ShipStation on August 11 under support ticket #10038205, although we had seen the same error occur previously and temporarily resolve itself. The current problem has now persisted for weeks.
Amazon orders containing items configured as bundles in ShipStation fail when attempting to use Amazon Buy Shipping with:
"amazon_order_item_id cannot be null or empty (Validation)"
This is not an occasional error. It is a reproducible, programmatic problem affecting all orders with bundled items which is roughly half of our Amazon shipments every day.
The affected orders import normally from Amazon and can be shipped through our own UPS/ShipStation carrier accounts. The failure is specifically with Amazon Buy Shipping when bundles are involved. These same bundled SKUs worked previously, and ShipStation support confirmed during troubleshooting that the issue occurs with bundle SKUs.
The business impact is becoming severe.
Because Amazon Buy Shipping cannot be used, we have to purchase the label outside Amazon Buy Shipping and lose Amazon's OTDR protection.
Our Amazon OTDR has already fallen approximately 5 percentage points since this began. That is pushing us dangerously closer to Amazon account-health thresholds and potentially puts our Amazon selling account at risk.
We've provided ShipStation with numerous affected orders, screenshots, working historical examples, and access to troubleshoot the issue. The ticket was escalated, but weeks later the latest response from the Escalations Team is simply:
"Our development team is still actively investigating the Amazon Buy Shipping label issue."
There is still no ETA and, more concerning, no meaningful technical status. We don't know whether development has reproduced the defect, identified the cause, or is actually working on a fix.
At this point, what does "actively investigating" mean weeks into a reproducible problem that has effectively crippled half of the software's usability for our Amazon orders?
This isn't just an inconvenience. Every day this continues, more orders lose Amazon Buy Shipping protection and the damage to our Amazon performance metrics accumulates. Fixing the software eventually does not automatically undo the account-health damage caused while waiting.
I'd really like to know:
Is anyone else using ShipStation bundles with Amazon Buy Shipping experiencing this same error?
If so, please share how long you've been affected and whether you've received anything more substantive from ShipStation development. This needs greater visibility and urgency before it causes serious damage to sellers' Amazon accounts.
