Destroy link not working throws Uncaught (in promise) TypeError: link.getAttribute is not a function Error

After selecting okay on sweet alert, I get following error in js console and request doesn't reach rails server.

Uncaught (in promise) TypeError: link.getAttribute is not a function
  at Object.Rails.handleMethod (rails-ujs.self-....js:471)
    at sweetAlertConfirmedCallback (sweet-alert2-rails.self-...js:37)
    at <anonymous>

link_to code for reference:

<%= link_to 'Delete', object_path(object), method: :delete, data: { confirm: 'Are you sure?' }, class: 'btn btn-danger' %>

Just hit the same issue. Did you ever figure out a solution? I'm going to keep digging for a fix or make a pr if I can fix it.

So what I ended up doing to fix it was wrapping it in a form.

Going from

<%= link_to "Delete Project", @project, method: :delete, data: { confirm: 'Are you sure?',
                                                                               'confirm-button-text': 'Do it!',
                                                                               'cancel-button-text': 'Nah, not yet',
                                                                               'confirm-button-color': '#3a96d1',
                                                                               'sweet-alert-type': 'error',
                                                                               text: 'You won\'t'}, class: "btn red" %>

to

<%= form_for @project, method: :delete do |f| %>
              <%= f.submit "Delete Project", class: "btn red accent-4", data: { confirm: 'Are you sure?',
                                                                                'confirm-button-text': 'Do it!',
                                                                                'cancel-button-text': 'Nah, not yet',
                                                                                'confirm-button-color': '#3a96d1',
                                                                                'sweet-alert-type': 'error',
                                                                                text: 'You won\'t'} %>
            <% end %>

There is an issue in sweetAlertConfirmedCallback() trying to reference data that hasn't been properly set.

Rails.handleMethod = function(e) {
        var csrfParam, csrfToken, form, formContent, href, link, method;
        link = this;
        method = link.getAttribute('data-method');  // <----- This guy throws a fit.
        ...
