OAuth 2.0 playground (the playground) is an OAuth client sample app for WSO2 Identity Server (the WSO2-IS). I can execute playground with WSO2-IS v4.0.0m3, but it's crashed with WSO2-IS v4.0.0m9 (the exception message as the following). Is playground already updated for IS v4.0.0m9? How to update/fix playground sample?
