Caused by: org.springframework.data.redis.RedisSystemException: Error in execution; nested exception is io.lettuce.core.RedisCommandExecutionException: ERR The XGROUP subcommand requires the key to exist. Note that for CREATE you may want to use the MKSTREAM option to create an empty stream automatically.

For anyone running into this issue, it's because you need to use the optional MKSTREAM subcommand

XGROUP CREATE key group <id | $> [MKSTREAM]
  [ENTRIESREAD entries-read]
