AJAX error: “No multipart boundary param in Content-Type”












2















I am trying to upload a file from localhost to a server but I am getting the following error in my network console, with status code 500:




no multipart boundary param in Content-Type




I have enabled cors on my nginx reverse proxy. My AJAX request is like this:



var files = document.getElementById('candidatePhoto').files;
if (!files.length) {
return alert('Please choose a file to upload first.');
}
var file = files[0];

var form = new FormData();
form.append("files", file);

var settings = {
"async": true,
"crossDomain": true,
"url": "http://example.com",
"method": "POST",
"headers": {
"Content-Type": "multipart/form-data"
},
"processData": false,
"contentType": false,
"data": form,
success: function(data) {
console.log("Success", data);
addPhoto(data);
},
error: function(err) {
console.log("Error", err);
alert("Error: " + err);
}
}


My HTML form also has enctype='multipart/form-data'

          If you set contentType: false jQuery will automatically apply the correct Content-Type header for sending multipart data. Your inclusion of a header object explicitly specifying the content type is breaking this behaviour. It needs to be removed. Change your AJAX request settings to this:



          var settings = {
          async: true,
          crossDomain: true,
          url: "http://example.com",
          method: "POST",
          processData: false,
          contentType: false,
          data: form,
          success: function(data){
          console.log("Success", data);
          addPhoto(data);
          },
          error: function(err) {
          console.log("Error", err);
          alert("Error: " + err);
          }
          }
