完整的消息错误是：

未捕获的TypeError：无法在“节点”上执行“ appendChild”：参数1的类型不是“节点”。在Jdata.records.forEach.item和Array.forEach

 request.addEventListener("load", function() {


            if (request.status == 200) {
                var Jdata = request.response;
                Jdata.records.forEach(item => {

                    var results = document.getElementById("results");
                    var title = item.fields.title;
                    console.log(item.fields.title);

                    if (item.fields.hasOwnProperty('p_tag')) {
                        var fname = item.p_tag.substring(0,6);
                        var fid = item.fields.p_tag;
                        var image = `https://media.vam.ac.uk/media/thira/collection_images/${fname}/${fid}.jpg`;

                        var img2 = document.createElement('img');
                        img2.src = image;



                    }

                    else{
