Webgui Apps such as MM03 and VA03



We have activated this S/4HANA 2020 Fully-Activated Appliance but are having an issue with Apps Display Material (MM03), when we select a material such as TG0011 and follow menu >More>Material>Change>Immediately, nothing happens, we just see an error by looking at the Developer trace of our Browser.

We have this exact same problem with Apps VA03.

We found some notes explaining that webgui is not working anymore due to a security note that has been implemented.

Here is the detailed error message, it is refering to webgui service:

webgui_min.js:532 WebSocket connection to 'wss://<HIDDEN FQDN>:44301/sap/bc/apc/sap/webgui_services?window_id=000D3A9C115E1EDBA0CF88A6D70DFF8B&session_id=000D3A9C115E1EDBA0CF88A6D70DFF8B≺_session_id=000D3A9C115E1EDBA0CF88A6D70DDF8B' failed: Close received after close

Uncaught (in promise) TypeError: d.getContent(...)[0]._showOrHideExpandButton is not a function

How can we could fix this ?

Thank you
