Catching connection error with SAPUI5 OData Model V4

[former_member673012]

Hello colleagues,

I would like to ask how can I catch errors using SAPUI5 OData Model V4, if the connection to the backend application has failed and the following errors are triggered:

• Could not load metadata: 500 Server Internal Error;
• Communication Error: 500 Server Server Error.

I looked in the OData Model V4 documentation and none of the events (parseError, requestFailed, etc.) available for OData Model V2 are supported for OData Model V4. ( https://sapui5.hana.ondemand.com/#/api/sap.ui.model.odata.v4.ODataModel%23events/Summary)From what I noticed for OData Model V4 only the sessionTimeout event is available.Having no event I do not know where would be the right place to implement callback function to be called in case the connection with the backend application failed.Appreciate any information and advice!
Thanks.

model.getMetaModel().requestObject("/").then(
                    function (data) {
                        //Success
                    }.bind(this),
                    function (data) {
                       //Error
                    }.bind(this));
