How to change the error text of the ErrorHandler.js into the exception message raised by the OData Service

💭 Only works if the error is raised in the OData Service via/IWBEP/CX_MGW_BUSI_EXCEPTION or/IWBEP/CX_MGW_TECH_EXCEPTION

/**
		 * Shows a {@link sap.m.MessageBox} when a service call has failed.
		 * Only the first error message will be display.
		 * @param {string} sDetails a technical error to be displayed on request
		 * @private
		 */
		_showServiceError: function(sDetails) {
				if (this._bMessageOpen) {
					return;
				}
				this._bMessageOpen = true;
				MessageBox.error(
					this.tryToResolveError(sDetails), {
						id: "serviceErrorMessageBox",
						details: sDetails,
						styleClass: this._oComponent.getContentDensityClass(),
						actions: [MessageBox.Action.CLOSE],
						onClose: function() {
							this._bMessageOpen = false;
						}.bind(this)
					}
				);
			},
			/**
			 * @description try to read the error message value
			 * @param {string} sDetails a technical error to be displayed on request
			 * @returns {string} sDetails
			 */
			tryToResolveError: function(sDetails) {
				var sErrorText;

				try {
					var oError = JSON.parse(sDetails.responseText);
					sErrorText = oError.error.message.value;
				} catch (oException) {
					sErrorText = this._sErrorText;
				} finally {
					return sErrorText;
				}
