In my case it was working perfectly fine in my local dev machine but giving following error on production environment. <Paperclip::Errors::NotIdentifiedByImageMagickError: Paperclip::Errors::NotIdentifiedByImageMagickError>

I checked version of imagemagick on my machine it was ImageMagick 7.0.8-59. I checked version on my production environment it was ImageMagick 6.9.4-7. I was using dockerfile to setup my production environment. I was using following line of code to install imagemagick in production env.

RUN apt-get update && apt-get -y install imagemagick && apt-get clean

even though my exceptions were that this command would install the latest version of imagemagick but it was installing every time ImageMagick 6.9.4-7. #2223 states that processing of pdf has been disabled by the imagemagick. I decided to update the version of imagemagick of production but I couldn't use the apt-get because it was installing the wrong version. I decided to install it from source but installing from source doesn't install dependencies so i had to install them manually. This was my code in dockerfile

RUN apt-get install wget
RUN apt-get update -qq && apt-get install -y \
  libmagickwand-dev \
  libmagickcore-dev
RUN wget https://imagemagick.org/download/ImageMagick.tar.gz
RUN apt-get install -y build-essential checkinstall
RUN tar xf ImageMagick.tar.gz
RUN cd ImageMagick-7.0.8-64 && \
./configure && \
make && \
checkinstall && \
ldconfig && \
cd .. && \
rm -rf  ImageMagick*
RUN apt-get update && apt-get -y install ghostscript && apt-get clean

the download url might change later in time.

Got to this thread with the same error ActionView::Template::Error (Paperclip::Errors::NotIdentifiedByImageMagickError)

After some investigation, I found the problem in my default ImageMagick policies at /etc/ImageMagick/policy.xml

Since I was cropping images from Unsplash, they were rightfully considered downloaded via HTTP / HTTPS, while my policy.xml had these lines among others:

  <policy domain="coder" rights="none" pattern="HTTPS" />
  <policy domain="coder" rights="none" pattern="HTTP" />

Thus, ImageMagick blew up on downloaded images while still handling direct uploads. Commenting these 2 lines out has resolved my problem. Hope this helps someone!

sudo apt-get install imagemagick && sudo apt-get install libmagick++-dev

This command solved my problem

Just leaving a comment here for fellow googlers in the future - we were getting an intermittent failure in production on PDF uploads (< 1%).

It appears that I was able to repro the error condition by password protecting the PDF, which caused the Paperclip::Errors::NotIdentifiedByImageMagickError to be raised 🤔
