recreate_versions! giving error: undefined method `body' for nil:NilClass

[snoblenet]

I am storing images on S3.

I am uploading the images to the directory etc that CarrierWave expects using a client-side desktop application, not Rails.

This works. After calling area.update_column :screenshot, "file.png" within Rails, I can get the correct URL using area.screenshot.url.

The images are uploaded as ACL: public-read.

My client-side desktop app only uploads the default version of the image. I then need Rails to create a blurry version.

So, I call area.screenshot.recreate_versions!(:blurry), but this gives me this error:

NoMethodError: undefined method `body' for nil:NilClass
from /Users/steven/.rvm/gems/ruby-2.2.2/gems/carrierwave-0.10.0/lib/carrierwave/storage/fog.rb:228:in `read'

Thoughts?

Update, I am trying to address this the long way around with:

area.remote_screenshot_url = area.screenshot.url
area.save!

But I am getting:

ActiveRecord::RecordInvalid: Validation failed: Screenshot Failed to manipulate with MiniMagick, maybe it is not an image? Original Error: `mogrify -blur-image 0 8 /var/folders/k9/vnpft_6d7qs6xmdb9_4svvmw0000gn/T/mini_magick20160503-8871-1jddvc6.png` failed with error:
mogrify: unrecognized option `-blur-image' @ error/mogrify.c/MogrifyImageCommand/4175.
from /Users/steven/.rvm/gems/ruby-2.2.2/gems/activerecord-4.2.5/lib/active_record/validations.rb:79:in `raise_record_invalid'

I have downloaded the image manually from S3 and opened it to check it is an image. The blur option works fine aside from in this situation. It reads:

  version :blurry do
    process :blur => [0, 8]
  end

  def blur(radius, sigma)
    manipulate! do |img|
      img = img.blur_image(radius, sigma)
      img = yield(img) if block_given?
      img
    end
  end

This error occours here, but versions are created on S3 nevertheless.

Sometimes we get this error:

[cdesch]

This seems to be still happening.

[mshibuya]

#1879 should have fixed this.

[antonakospanos]

When are we going to have this released?

[coding-bunny]

Any update on this?
Running in the exact same problem on our Sidekiq + CarrierWave and really need this working.
Works fine in a console, but not over a Sidekiq Job

[eric-khoury]

Any solution for this yet?

[robins35]

This issue is 6 years old, why is there no fix yet?

[mshibuya]

The fix was already released long ago, as 2.0.0. Open another issue if you still have this.
