confirmTransportationOptions frequently fails with InternalServerError for multi-shipment placement

[johnkw]

The https://sellingpartnerapi-na.amazon.com/inbound/fba/2024-03-20/operations/... call fails with:

{"operationStatus":"FAILED","operationId":"[...]","operation":"confirmTransportationOptions","operationProblems":[{"severity":"ERROR","code":"InternalServerError","message":"ERROR: Something went wrong. Please try again later."}]}

This is essentially a duplicate of bug #4144 but that one was closed without any resolution or workarounds being posted. It was also mentioned in bug #4133 and in #3951 (comment)

Deleting the entire Workflow and trying again doesn't seem to help at all, it just keeps happening.

After several Workflow cancel/delete and start over, it eventually worked. So it doesn't always fail, but it fails quite a lot.

Hi @johnkw, @LennyPu,
In order to correctly resolve this issue, Please open a support case following the guidance here so we can pursue the investigation as additional details are required from your end.

[johnkw]

Well I did already open a support case days ago but there's been no response. The important thing for anyone that finds this ticket to know is: keep deleting the entire workflow and trying again. It seems it's possible to eventually get it to work.
