Trying "redis-cli scan 0 TYPE hash" in Lettuce, but still getting all types back

[schwartzm]

Hi,
I'm trying to do a scan, limited to hash types, but still getting back all entries of all types. Basically, I'm trying to do a scan like redis-cli scan 0 TYPE hash, but in Lettuce. The redis-cli approach does work as expected (only returns hash keys).

Am I setting up CommandArgs incorrectly?

RedisCommands<String, String> rc = redisConnection.sync();
var scanArgs = new ScanArgs();
RedisCodec<String, String> codec = StringCodec.UTF8;
var cmdArgs = new CommandArgs<>(codec).add(0).add("TYPE").add("hash"); // Is my problem here?
scanArgs.build(cmdArgs);
var scanResult = rc.scan(scanArgs);

The output of cmdArgs.toCommandString() is 0 TYPE hash, which looks correct.

scanResult.getKeys() does contain keys, but for both hash and set. I'm only expecting hash.

Thanks for any guidance.
