Reordering images in Carrierwave multiple file upload - ruby-on-rails

Question

I'm trying to make a frontend mini admin system to reorder the product images stored as an array by Carrierwave multiple upload.
Frontend is working fine.
In my view, I have:
<%= form_for product, url: product_path(product.id), method: :patch do |form| %>
<div class="field">
<%= form.label :images %>
<div class="image-sortable">
<% product.images.each do |image| %>
<div class="image">
<%= hidden_field :product, :images, multiple: true, value: image.cache_name || image.identifier %>
<%= image_tag(image.url, height: 50) %>
<button type="button" class="remove-image">Quitar</button>
</div>
<% end %>
</div>
</div>
<div class="actions">
<%= form.submit %>
</div>
<% end %>
Params are being passed correctly
Processing by ProductsController#update as HTML
Parameters: {"utf8"=>"✓", "authenticity_token"=>"X0UIytX4V56npfBIrl/fkaUiIgP4BDiJOGpB8tCdAZMeP7kvDXV1z0wsGge4Kch1TJG9Gzhpbtt5hOpQXbMH/Q==", "product"=>{"images"=>["6919-000-6.jpg", "6919-000-2.jpg", "6919-000-3.jpg", "6919-000-4.jpg", "6919-000-5.jpg"]}, "commit"=>"Update Product", "id"=>"1169"}
In the product update, the order of images are not stored, and I'm getting null values appended.
Product Update (0.9ms) UPDATE "products" SET "images" = $1, "updated_at" = $2 WHERE "products"."id" = $3 [["images", "[\"6919-000-2.jpg\",\"6919-000-3.jpg\",\"6919-000-4.jpg\",\"6919-000-5.jpg\",\"6919-000-6.jpg\",null,null,null,null,null]"], ["updated_at", "2023-01-26 21:08:11.373942"], ["id", 1169]]
In my controller, I have the standard update method:
def update
respond_to do |format|
if #product.update(product_params)
format.html { redirect_to #product }
format.json { render :show, status: :ok, location: #product }
else
format.html { render :edit }
format.json { render json: #product.errors, status: :unprocessable_entity }
end
end
end
