Cloning Object with Shrine/Imgix Attachment using .dup fails about shrine-imgix HOT 2 CLOSED

The error comes from Shrine's copy plugin, which overrides #dup on the model instance (in your case the ActiveRecord::Base model) to create a copy of the original model's attachment and assign the copy to the duplicate.

The problem is that for some reason your attachment (the Shrine::UploadedFile object) is missing the size metadata value, so when the Shrine::UploadedFile object gets passed directly as the :body parameter for upload, aws-sdk-s3 assumes it will have a #size and does a comparison with >, causing the error you're seeing.

Can you check your upload flow and try to figure out where the size metadata is left out? Note that when doing direct uploads to S3 you need to assign it manually on the client side (or alternative use the restore_cached_data plugin).

Aha, thanks for the quick response. There are a few places in the flow where we set this, i'll try and track down which one is causing the issue. Thanks!
