(Thereafter in the stack trace is my code / other code I'm using.)

I'd swear this was working fine and broke in the vicinity of when we updated to... 2.1.0-ish? (we updated on 6/18...)

Our relevant code looks a bit like so:

iam         = Aws::IAM::Resource.new(credentials: cred,
                                     region:      ENV.fetch("AWS_REGION"))
policies    = iam.policies(scope: "Local").to_a
# ...
policy      = policies.find { |pp| pp.policy_name == name }
versions    = policy.versions # <-- This goes boom.

I've added the missing paginator for Aws::IAM::Client#list_policy_versions which should stop this from raising. This fix should be released shortly. Thanks for reporting the issue!
