                }

Answer 1

image is a problem while using json.stringify.Send the formdata object and append all the items into it. Try this

    var imgFile = document.getElementById('logo');
var imgfileList = imgFile.files;

var formdata = new FormData();
if (imgfileList && imgfileList != null && imgfileList.length > 0) {

    formdata.append(imgfileList[0].name, imgfileList[0]); or add the name
    formdata.append('logofilename', imgfileList[0]);
}
var other_data = $('#companyData :input').serializeArray();
$.each(other_data, function (key, input) {
    formdata.append(input.name, input.value);
});


    $.ajax({
        url: UrlRoot.SaveTeamInfo,
        data: formdata,
        processData: false,
        contentType: false,
        type: 'POST',
        success: function () {

        }
    });

Please remeber to add process data and content type to false as specified in the ajax call above.

try this is formdata is undefined'

if(typeof FormData == "undefined"){
var data = [];
data.push(imgfileList[0].name, imgfileList[0]);
}
else{
var data = new FormData();
    data.append('data', JSON.stringify(inputData));
}

Use .push instead of .append for array
