      Future<Void> initFuture = Statsig.initializeAsync(STAT_SIG_SECRET);
      log.info("Initialized stat-sig client");
    } catch (Exception e) {

build.gradle:

implementation 'com.statsig:serversdk:1.6.1'

gson librarry used in project is
implementation 'com.google.code.gson:gson:2.9.0'

2.9.0 is the right version, does you project also use other versions of gson that could be conflicting here?
