问题
I am facing the issue while converting pdf to image using Wand:
E wand.exceptions.PolicyError: not authorized `/opt/sample.pdf' @ error/constitute.c/ReadImage/412
I have already visited the previous stack overflow question here: convert:not authorized `aaaa` @ error/constitute.c/ReadImage/453
Here is my code
def build_image(self, pdf_path, img_path):
with wand.image.Image(filename=pdf_path) as img:
img.save(filename=img_path)
My code was working form last 6 months. now why i am getting error.
Please help.

This is probably due to an security fix of the underlaying package (see https://bugs.launchpad.net/ubuntu/+source/imagemagick/+bug/1796563)
I fixed it for me by editing the /etc/ImageMagick-6/policy.xml and changed the rights for the pdf line to "read":
<policy domain="coder" rights="read" pattern="PDF" />
