Gallery image seems to first open in new tab, upon refresh it either works correctly or gives invalid source error

[programthis]

As stated in the title, when I first click on the gallery image, it opens in a new tab. But when I refresh the page, it sometimes seems to behave correctly. But I've also received the invalid source error (the greyed out carousel with the "invalid source error text"). I've seen this happen in various browsers, albeit inconsistently. Any ideas would be very helpful.

fslightbox: version: 3.4.1

Here's an example of how I'm using fslightbox:

<% gallery_block.photo_blocks.each_with_index do |photo_block, index| %>
          <% if index < 4 %>
            <%= link_to content_tag(:div, '', style: %Q[background-image: url(#{rails_blob_url(photo_block.image)});]), rails_blob_url(photo_block.image), class: 'img', data: { fslightbox: "gallery_#{ gallery_block.id }", src: rails_blob_url(photo_block.image), "aria-label": "Image", turbolinks: false } %>
          <% elsif index == 4 %>
            <% if gallery_block.show_more? %>
              <%= link_to content_tag(:div, '', style: %Q[background-image: url(#{rails_blob_url(photo_block.image)});]), rails_blob_url(photo_block.image), class: 'img', "aria-label": "Image"  %>

              <div class='and-more'>
                <%= link_to "+#{gallery_block.photo_blocks.count - 5}", "aria-label": "Image", data: { fslightbox: "gallery_#{ gallery_block.id }", src: rails_blob_url(photo_block.image) } %>
              </div>

            <% else %>
              <%= link_to content_tag(:div, '', style: %Q[background-image: url(#{rails_blob_url(photo_block.image)});]), rails_blob_url(photo_block.image), class: 'img', data: { fslightbox: "gallery_#{ gallery_block.id }", src: rails_blob_url(photo_block.image), "aria-label": "Image", turbolinks: false }  %>
            <% end -%>

          <% else %>
            <%= link_to '', '', class: 'hide', "aria-label": "Image", data: { fslightbox: "gallery_#{ gallery_block.id }", src: rails_blob_url(photo_block.image), turbolinks: false }  %>
          <% end -%>
        <% end -%>
