Hey! I had the very same error and the culprit was duplicated dependencies

I had smithy-client version 3.49.0 alongside 3.55.0 There were many versions as each @aws-sdk sub-package would have its own @aws-sdk/smithy-client

I fixed it by updating all my @aws-sdk sub packages (i.e. client-sts, client-dynamodb) to the same latest version.
