ActiveSupport :: MessageVerifier :: InvalidSignature

Question

我正在从activeadmin上传图像，并且得到

ActiveSupport::MessageVerifier::InvalidSignature

有什么办法解决这个问题？

这是我的表格部分

的编码

<%=semantic_form_for [:admin, @product] do |f| %>
<!--product main image-->
      <%= f.input :product_image, :as => :file, 
          :hint =>if @product.product_image.attached?
                    image_tag(@product.main_image_thumb)
                  end%>


  <!--has many other product images-->
  <%=f.input :other_product_images, :as => :file,input_html: { multiple: true }%>
    <%if @product.other_product_images.attached?%>
      <%@product.other_product_images.each do|img|%>
        <div class="inline-imgs">
          <%=image_tag(img, class: "other-img-thumb")%>
          <div class="del-other-img-link">
            <%=link_to "delete",del_other_image_admin_product_path(img.id),method: :delete,data: { confirm: 'Are you sure?' }%>
          </div>
        </div>
      <%end%>
    <%end%>
<%end%>

activeadmin产品创建和更新控制器是

def create
  super do |success,failure|
    success.html { redirect_to edit_admin_product_path(@product) }

  end
end

def update
  super do |success,failure|
    success.html { redirect_to edit_admin_product_path(@product) }
  end
end

我已经在开发环境中设置了active storage to local。我也试图以部分形式添加multi-part true，但是它不起作用。 我正在使用rails 5.2.3 and ruby 2.6.1

任何建议或解决方案将不胜感激。
