A client has informed us that they often receive an empty error after login or page reloading. The error message is empty, there is only the red error popup.
They are using SAO, not the tryton client.
After some debugging I saw that the error comes from a rpc request either on menu.read or icon.read. The request simply fail, there is no response from the server, the status of the request is 0. In fact I think the server is never reached.
I did some testing and this problem only happens if I have lots of menus opened. Moreover, It does not seem to occur on Firefox, but it happens on chrome or edge. This seems to me like a browser limit of some sort. But this does not occur everytime, if I reload the page one or two times the error does not show up, if I reload again the error may appear again.
When this error happens, either the icons are not loaded or a part of the menu is not loaded.
Has anyone already seen this error and maybe know of a way to correct it ?
