Aws-sdk-ruby: Breaking change in S3 client from v2 to v3

[softwaregravy]

I seem to have found a breaking change when trying to move to V3 of the SDK (or maybe I'm missing something)

In SDK 2.11.110, the following seems to be working just fine

Aws::S3::Resource.new.bucket(ENV['S3_BUCKET'])

In SDK 3.22.0 it throws the following exception:

PATH/gems/aws-sdk-s3-1.17.0/lib/aws-sdk-s3/bucket.rb:666:in `extract_name': missing required option :name (ArgumentError)
        from PATH/aws-sdk-s3-1.17.0/lib/aws-sdk-s3/bucket.rb:21:in `initialize'
        from PATH/aws-sdk-s3-1.17.0/lib/aws-sdk-s3/resource.rb:69:in `new'
        from PATH/aws-sdk-s3-1.17.0/lib/aws-sdk-s3/resource.rb:69:in `bucket'
        from PATH/config/initializers/aws.rb:6:in `<main>'

@softwaregravy The code works for me for both v2 and v3, may I ask is the environment having 'S3_BUCKET' value when you are running v3 code?

[softwaregravy]

huh. Everything is the same. I can cause the exception and remove it simply by changing my gemfile.

I'll try and make a one-off example that breaks to rule out anything else in my project interfering.

I have created a dummy project that can recreate the issue

it was still breaking in my reproduction app, but the problems suddenly topped. I can't explain. I guess we'll just assume user error for now

@softwaregravy,

Thanks for attempting to reproduce the issue. If you do come up with something consistent, let us know.

try not using ENV['S3_BUCKET'] and instead replacing it with the actual string value that was stored in that environment variable. That fixed the issue for me.

ENV['S3_BUCKET'] => whatever-this-value-really-is

@davidlcorbitt that worked for me!
