DynamoDB Enhanced: Bugfix for handling '+' character in attribute names #3063

debora-ito · 2022-03-01T18:24:45Z

DynamoDB expression attribute names should have only alphanumeric characters. The Enhanced Client manually replaces special characters with placeholders by calling cleanAttributeName(String key) but it was not replacing the + character.

Motivation and Context

Fixes #3058.
