When running the `uploads:migrate_to_s3` rake task on the most-current version of Discourse, the following error results:

```plaintext

I am also facing a similar problem when trying to run uploads:migrate\_to\_s3. Any suggestions?

As best I can tell, this is a bug (probably somewhere in [this](https://github.com/discourse/discourse/blob/83a346cd6879be75e6e9312e6b9d6edee1ae2c7b/lib/tasks/uploads.rake) file) that will need to be fixed before we’ll be able to run the rake task successfully. Given the interactions in the [previous thread](https://meta.discourse.org/t/cannot-execute-the-rake-uploads-migrate-from-s3/78541/10), I would assume this is something that will need the attention of @sam or @zogstrip.

I perused the file, but, sadly, I don’t know enough Ruby to find the problem.

This is now fixed in:

Thanks for reporting, @Zyniker 👍
