LiipImagineBundle + KNPGaufrette + VichUploaderBundle + Amazon S3 can't generate thumbnails on S3 - symfony

Question

When trying to use LiipImagineBundle + VichUploaderBundle and Amazon S3, I'm encountering a weird issue. When I upload a file via my Symfony form (using the VichFileType form field), the file is successfully created on Amazon S3 (via Gaufrette). When I display the uploaded file in my twig view, it displays perfectly.
However, when I'm trying to generate a thumbnail of the file (which was uploaded on S3), I get the following error :
The service "liip_imagine.cache.resolver.amazon_s3" has a dependency
on a non-existent service "1".
I've followed the documentation : https://symfony.com/doc/2.0/bundles/LiipImagineBundle/cache-resolver/aws_s3.html
Here's my app/config/config.yml file:
# VichUploaderBundle Configuration

- [ setPutOption, [ CacheControl, "max-age=86400" ] ]
tags:
- { name: "liip_imagine.cache.resolver", resolver: "amazon_s3"}
Any reasons for why I can't get it working?
