Error while doing a refresh task

[Theyagarajan S]

Hi,

I'm hitting an error while running a refresh in paperclip 2.3.8.

The error seems to arise in paperclip.rake  : if !name.blank? && klass.attachment_definitions.keys.include?(name)

name is nil and so is attachment_definitions. Any help on this?

Stacktrace ===

Requiring REXML

** Invoke paperclip:refresh:thumbnails (first_time)

** Invoke environment (first_time)

** Execute environment

** Execute paperclip:refresh:thumbnails

rake aborted!
