while searching the forums I found this older question, which is still not answered:
It refers to wM 9.0.
So it looks for me that this broke between 8.2 and 9.0.
Please open an incident in Empower eService to get this checked by SAG support.
Additionally you should check the WM Error Code Reference available in the documentation section if it contains any informations for this code: [ISS.0086.9287]
