Fulfillment Inbound API v2024-03-20 listPackingOptions returns empty packingOptions

[meareal]

After successfully executing CreateInboundPlan and GeneratePackingOptions, ListPackingOptions does not return packingOptions.

In other words, the ListPackingOptions calls returns 200 with an empty packingOptions.

}

Note: I read issue #4148 where johnkw mentions how often these calls fail, I tried submitting ListPackingOptions so many times and the response is always the same (empty)

Any suggestions?

Thanks

Hi @meareal, thanks for reaching out! Have you checked the operation status of generatePackingOptions operation? This is an asynchronous operation, so something might be wrong when generating the packing options. Best, Marc Selling Partner Developer Services

Good morning @mafge

I tried GetInboundOperationStatus (like you suggested) and got the following error

{
    "operationStatus": "FAILED",
    "operationId": "1b843a65-2ed4-4526-ae68-8fe93e40aaba",
    "operation": "generatePackingOptions",
    "operationProblems": [
        {
            "severity": "ERROR",
            "code": "BadRequest",
            "message": "ERROR: Operation GeneratePackingOptions cannot be processed because the inbound plan does not support packing options."
        }
    ]
}

And then found issue 4046 which is what I am following up on now to see this helps us, especially the posts on or after Aug 26th

@mafge

If there was something wrong with GeneratePackingOptions I would get an error, correct? But I don't. I get the operationId instead so I am assuming GeneratePackingOptions worked.

I have tried different options for labelOwner and prepOwner (CreateInboundPlan) and continue to get the same error message (posted earlier today) when I call GetInboundOperationStatus.

@meareal, your assumption is unfortunately not correct. You get an operationId in any case, this just means that the backend has accepted your request for further processing. You always have to check whether the operation was executed successfully afterwards (as the operation will be executed asynchronously). Have you looked into the steps described in this comment? It looks to me like you have to provide more information for the specific SKU(s) via Seller Central first.

[meareal]

Good morning. Thanks @mafge for the reply. I did check issue #4046 and especially the posts on Aug 26th. I can't find the items (in step 3) and the items I see (under Send to Amazon) I can't find the updated prep instructions. So I am stuck at the moment. Furthermore, it is not clear to me why I have to do this prep/configuration work in Seller Central first.

Hi @meareal, I see. One suggestion: You could try to create the shipment via Seller Central (sometimes errors with your SKUs are easier to see in the UI), because the flow is essentially the same. If it works via the UI, then there is something wrong with the API and you would need to contact developer support.
