Handling null or empty values in Date Chart

Hi Team,

I have a chart that has the following y-axis setting below and it is showing an error of "Bad number format specifier m ". I suspect that it's due to some records that doesn't have dates. How should empty or null data be handled? Thanks

//Initializing Primary Y Axis
                   range: { min: new Date(new Date().getFullYear(), 0, 1), max: new Date(new Date().getFullYear(), 11, 31), interval: 1 },
                   intervalType: 'Months',
                   valueType: 'datetime',
                   labelFormat: 'MMM dd',
                   title: { text: 'Year' }
  //Initializing Common Properties for all the series
                   type: 'bar',
                   enableAnimation: true,
                   tooltip: { visible: true, format: "#series.name# - #point.x# <br/> Date : #point.y#" },
                           font: { size: '10px', fontFamily: 'Segoe UI', fontStyle: 'Normal', fontWeight: 'regular' },
                           textPosition: 'top',
                           angle: -90,
                           visible: false

Thank you for using Syncfusion products. 
We have analyzed your query and the sample code provided by you, we noticed you have set datetime type for Y-Axis(vertical axis) and thus the issue, chart doesn’t support datetime type for Y-Axis. Also we noticed that you have used the Bar chart type in that case the Y-Axis will be Horizontal. Do you want to show the datetime value horizontally or vertically? 
Can you please let us know your exact requirement, so that we can provide you a solution sooner.
