Steps to reproduce
- Upload a password secured pdf
- run preview-generator
Expected behaviour
If preview generator can not open a file to generate a preview in case of encryption / password secured file, it should ignore this file or create a thumbnail which gives information that this file is encrypted.
Actual behaviour
Generation of previews stops with an error. No more previews are generated.
I have to remove the encrypted file and start again generating previews.
