Oauth2 -Error - Unknown/invalid scope(s)

Based on your screenshot you are running a Virtuoso 08.02.3309 build from Oct 2018 ( and associated VAL VAD 2.2.2_git161 version), which is very old and there have been a number of VAL and other related fixes in the latest Virtuoso 08.03.3329 Release Sept 2023 build you would most probably benefit from and would recommend upgrading to.
