                    jQuery.ajax({

                                type: "POST",
                                contentType: "application/json; charset=utf-8",
                                url: "VATReportGeneration.aspx/SetImageInSession",
                                data: JSON.stringify({ "image": image }),

                                success: function (data) {

                                    if (data != '') {
                                        jQuery.ajax({
                                            type: 'POST',
                                            cache: false,

    Write your image data imgdata handling logic code inside .then

    More here: https://www.amcharts.com/docs/v4/concepts/exporting/#Triggering_export 

      chart.exporting.getImage("png").then(function (imgdata) {
     var image = imgdata.replace('data:image/png;base64,', '');
     //your ajax call and other logic here
     ......
     .......
   }
