Live View: How to Upload Files

While Uploading files with LiveView, is not returning %Plug.Upload{} struct in handle_event/3 function, instead it is returning string something like this "[object File]". Do I need to parse this string to get the struct or there is some different way to handle File uploading with LiveView.

Below is my code for reference.

<%= form_for @changeset, "#", [class: "add-candidate-form w-100", id: "applicant-form", multipart: true, phx_change: :validate, phx_submit: :save], fn f -> %>

            <div class="form-group col-6">
              <label>Resume <span class="text-danger">*</span></label>
              <div class="input-group">
                <div class="custom-file">
                  <%= file_input f, :resume, [class: "custom-file-input", id: "inputGroupFile01", file_input: "one"] %>
                  <label class="custom-file-label" for="">Max size 2 mb</label>
                </div>
              </div>
            </div>

<% end %>

When not using LiveView, this is working fine and I am getting %Plug.Upload{} struct in the params on submitting the form.
