3570428 - Message "Long Text" Not Displayed in Create Supplier Invoice App - SAP S/4HANA

When creating an invoice with app "Create Supplier Invoice", if an error comes up after "Check", it is noticed that the error does not show any Diagnosis/LongText when accessing it, even though the error is not self explanatory.

If the Developer tool is checked, one or some of the following errors might show up:

-A request has failed for long text data ("Console tab")
-Origin segment parameter not supported for Co-deployed services ("Network tab" for $Value -> Response tab)

If /N/IWFND/ERROR_LOG is checked in the backend system, Error: "No service found for namespace '/IWBEP/', name 'MESSAGE_TEXT', version '0001" might show up.
