Cloudinary how to update/edit images in array

I followed the tutorial on cloudinary.com to upload multiple (product) images to cloudinary. It works fine when I add a new product and upload a new image. When I try to edit/update the product, I want it to add the new image to an image array, but I get the error:

enter image description here

In my development.log:

app/controllers/admin/products_controller.rb:29:in `update'

Even if I don't upload a new image file, I still get the error. I think I did something wrong when setting up Cloudinary...

Here's my setup:

First I added the gems in my gemfile

gem 'carrierwave', github:'carrierwaveuploader/carrierwave'
gem 'cloudinary'

Then I created the cloudinary.yml file where I added my cloud_name, api_key and api_secret.

In my ProductsController I have set images as an array images: []:

def update
 @product = Product.find(params[:id])
 if @product.update_attributes(product_params)
   redirect_to admin_products_path
 else
   redirect_to admin_products_path
 end
end

private

 def product_params
  params.require(:product).permit(:name, :description, :price, :supply, :shipping_amount, :active, :product_number, images: [] )
 end
end

In my views, the images file field looks like this:

<%= f.file_field :images, type: :file, multiple: true %><br />

Edit: Another thing I found out is that when I inspect the page, there's a messed up link:

http://res.cloudinary.com/dzidt5gxk/raw/upload/v1/%5B%22%5B%5C%22image/upload/v1525416518/t50yzb4cjtdnlyae4zx2.jpg_____

What the link should be: http://res.cloudinary.com/dzidt5gxk/image/upload/v1525416534/exhgstwb354t4l6rqvmh.jpg

In the rails console it also shows that the images array is messed up:

<Product id: 3, name: "Ananas", images: "[\"[\\\"image/upload/v1525416518/t50yzb4cjtdnlyae4zx2...", product_number: "342342">]>

According to the Carrierwave documentation :

Also, make sure your upload controller permits the multiple file upload attribute, pointing to an empty array in a hash. For example:

params.require(:user).permit(:email, :first_name, :last_name, {avatars: []})

Maybe you just need to change your permit params.
