@aplapana I need you to make the following changes:

• Rebase from main to 2.4.9-develop
• Add a new paragraph below line 20 stating that as of 2.4.9, the errors data type was removed from PlaceOrderOutput and that errors are now returned at the top of the response.
• Remove the example that you added.

Can you please hold off any changes just yet ? I think we will modify the solution a little bit - intstead of removing the error structure completly we will introduce a new mutation and deprecate this one. I will have a call with the PO today to sort this out. Will update the documentation changes again once we have a clear picture.
