I’m trying to get watermarked image by sending get request from next.js front-end as follows:
Here I’m sending event_image id so that I can access it in back-end and apply watermark to it then return to front-end
`const handleImageDownload = async (eventImageId) => {
try {
const response = await getWatermarkedImageApi(eventImageId);

  if (response.status !== 200) {
    throw new Error('Failed to watermark image');
  }
  const data = response.data;
  console.log(data);
} catch (error) {
  setError(error.message);
} finally {
  setLoading(false);
}

}`

Now coming to rails back-end in event_image/watermark_image operation

def add_watermark_to_image(ctx, event_image:, **)
        return if event_image.blank?
      
        image_name = event_image.image_name
        return if image_name.blank?  # Check if the image name is present
      
        image_uploader = EventImageUploader.new(event_image, :image_name)

        image_uploader.retrieve_from_store!(event_image)
      
        image_path = image_name.path

        return if image_path.blank?  # Check if the image path is present
      
        watermark = MiniMagick::Image.open(Rails.root.join('public', 'assets', 'images', 'watermark.png'))
        watermark.resize "100x100^"
        watermark.gravity "center"
      
        image_target = MiniMagick::Image.open(image_path)
      
        image_target.composite(watermark) do |c|
          c.gravity "center"
        end
      
        new_image_path = Rails.root.join('tmp', "watermarked_#{Time.now.to_i}.png")
        image_target.write(new_image_path)
      
        ctx[:watermarked_image_path] = new_image_path.to_s
      end

Here when I tried to hit the api I get error as follows:
Completed 500 Internal Server Error in 72942ms (ActiveRecord: 1.7ms | Allocations: 36342)

Errno::ENOENT (No such file or directory @ rb_sysopen – event_image/image_names/413/blob):

app/concepts/v1/event_image/operation/watermark_image.rb:50:in add_watermark_to_image' app/controllers/v1/event_images_controller.rb:5:in watermark_image’
despite image_path being correct I’m getting this error

I tried to byebug the code it’s fine upto
return if image_path.blank?
but still gives error that there isn’t any image at the path provided
also from developer tools I checked if image path is correct and it’s correct then why
this error for file Errno::ENOENT (No such file or directory @ rb_sysopen – event_image/image_names/413/blob):
