I’m getting this error when trying to use the `SCAN` command on Fly.

Is this command disabled by any chance?

It’s disabled but I think it’ll be okay to enable. I’ll get that out later today or tomorrow and follow up with you @pier.

Thanks @michael

I’ve already changed my code to use hashes instead so I don’t have to use `SCAN`.

Are there other disabled commands?

@pier`SCAN` and `KEYS` work now if you choose to refactor again 😉

We don’t allow commands for scripting, replication, admin, or pubsub. I also don’t think we added the newish streams commands yet.
