Getting TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode

Question

I have such jQuery code:

$(document).ready(function() {

  $('.btn-create-post-card').on('click', function(event) {
    event.preventDefault();
    let form_data = new FormData(),
      file = $('.input_file_button');
    // if(!file.val()) {
    //     alert('Please select postcard you want to send')
    // }
    form_data.append("file", file.prop('files')[0]);
    $.ajax({
      url: "/sendEmail",
      dataType: 'multipart/form-data',
      cache: false,
      contentType: false,
      processData: false,
      data: form_data,
      type: 'post',
      success: function(data) {
        alert('OK');
      },
      error: function(error, status) {
        console.log('here');
        console.log(error);
        alert(error);
      }
    });
  });
});

And I'm getting error:

TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode functions or the arguments objects for calls to them
    at Function.remoteFunction (:2:14)

Console output is:

As you can see response is successful and I used jQuery AJAX calls a lot before and never had such issue.

Updated:

Answer 1

I don't think strict mode is the error, it's just that the console can't get the contents of the arguments array in strict mode. The status is 200 so it looks like the ajax call worked, but the response text says "can't upload file", so I think the error is on the server side.

Update with TypeError example:

That TypeError just says the console can't get the values the arguments array when using strict mode. It's not an error with the code. The simple example in the image demonstrates this.

Answer 2

I found the issue: it was in dataType: 'multipart/form-data' and, after I remove it, everything is working.

I think it worked on a different machine because the browser version on that machine does not support strict mode.
