aws-sdk-s3: NoMethodError: undefined method `account_id' for an instance of Aws::STS::Types::Credentials

[MrJoy]

Describe the bug

Starting with 1.164.x, I'm seeing an exception when trying to assume a role via STS. 1.163.x does not exhibit this behavior. Specifically, the S3 SDK is attempting to access an apparently non-existent account_id property on Aws::STS::Types::Credentials.

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

I expected the code that I wrote and have been successfully using untouched for months to continue working.

Specifically, I'm using Aws::STS::Client to assume_role before performing S3 operations.

Current Behavior

NoMethodError: undefined method `account_id' for an instance of Aws::STS::Types::Credentials (NoMethodError)

          if context.config.credentials&.credentials&.account_id
                                                    ^^^^^^^^^^^^

Reproduction Steps

def session_token(env)
  role_arn = get_role(env)
  puts "Getting session credentials for role: #{role_arn}"

  client = Aws::STS::Client.new

  client.assume_role({
                       role_arn:,
                       role_session_name: "s3_gc",
                     })
end

# ...

client = Aws::S3::Client.new(credentials: session_token(env))

client.list_objects(bucket:).contents.each do |object| # <-- Exception happens here.
  # ...
end

Same issue as in: #3110

In general, we recommend that you use supported credentials objects rather than the responses returned by client calls - in this case, you can use the AssumeRoleCredentials which will give you automatic refreshing of the credentials as well!

Service clients expect credentials to be provided as a Aws::CredentialProvider, eg: see the S3 Client#initialize docs.

[MrJoy]

@alextwoods Thank you for the guidance. I'll take a look into that.

[mullermp]

You should just be able to do: credentials = Aws::AssumeRoleCredentials.new(role_arn: get_role(env), role_session_name: 's3_gc') as a drop in replacement, then create your client with it.
