422 Unprocessible Entity Error, Fulfillment REST API

[mambro]

We POSTed this:

{
    "fulfillment": {
        "location_id": 3895984177,
        "tracking_number": "1Z6V50R70392709729",
        "tracking_company": "UPS",
        "line_items": [{
                "id": 10456407900421,
                "quantity": 1
            }, {
                "id": 10456407867653,
                "quantity": 1
            }, {
                "id": 10456407933189,
                "quantity": 1
            }
        ]
    }
}

to one of our shops using this kind of URL:

admin/api/2021-04//orders/{id}/fulfillments.json

We've been sending fulfillments, successfully, for over a year. To an older API version: 2020-10. Last week it started failing:

{"errors":{"line_items":"array contains unpermitted members"}}

So we noticed we're on an old REST API version, and our first instinct is to update. That changed the problem to this error:

422 Unprocessible Entity.

{"errors":{"base":["An error occurred, please try again"]}}

No other information. NOTHING. This is happening on ALL of our shops, not just this particular one. We have HUNDREDS of orders needing fulfillment information.

Response headers:

We need this fixed. Stat.

Hi

Thanks for bringing this to our attention!

There was a reply here by @lizk . Right now we can't see it. Assuming that's a bug. They asked us to report it with Partner Support. The particular way outlined by @lizk is unavailable to us. We see no "Report an Issue" link or button. We do see a "Contact Partner Support" button. We'll use that.

Update: after using that button and logging in (for a 3rd time) we see a button "Report an Issue".

Thanks! 

Yup that will work as well!

Sorry I should have clarified that you must be logged into your Partner Account and click on "Contact Partner Support" to be able to see the specific "Report and Issue" button.

Report submitted to Partner Support.

It happened again, just now, with a different order.
