On May 11th 2021 we will make adjustments to error handling and reporting of Order status modification and Order header modifications. The changes are rather minor, but if your processing reacts to the status codes or instance references, you might want to check if your error handling will be still working properly. The changes in general:
422
instead of 400
.instance field
is changed in several cases, mostly it is now prefixed with data.
and sometimes it is data.<item>
where it was payload
before.
