404 Not Found when using open-uri for files on AWS S3

[rkorzeniec]

It seems that either there is a bug, or I have implemented it wrongly, perhaps I can get some input/advise on it.

Issue Unexpected error while processing request: 404 Not Found error received then trying to lazy retrieve the files stored on AWS S3 with open-uri, as in the readme guide

The error is returned when processed, however while debugging with i.e. pry and calling open(invoice.url) it seems that the call is successful as the instance of File is returned and read can be called on it, with what seems like the right file contents.

Code sample

invoices.lazy.map do |invoice| 
  [open(invoice.url), 'invoice_1.pdf']
end

The url must be wrong is all that I can think? Can you look at invoice.url in the debugger and verify that it's a working URL?

Some objects have a signed_url or other method that is the one you want instead
