I guess you have customFormatter defined using sap.viz.ui5.api.env.Format.numericFormatter(); Such issue observed might due to the fact that custom formatter functional names, like "ValueAxisFormatter" or "DataLabelFormatter" in my example, is not found.
Maybe you could check your custom formatter function.
