Quitting a group as last admin

[newhinton]

When i use the signal-cli api to create a group, it seems i can't leave it again. (I am using the jsonRpc)

The passed json:

{
    "method": "quitGroup",
    "id": 123,
    "jsonrpc": "2.0",
    "params": {
        "groupId": "456=",
        "delete": true
    }
}

The result is as follows:

{"jsonrpc":"2.0","error":{"code":-1,"message":"You need to specify a new admin with --admin: User is last admin in group: The (458=)","data":null},"id":123}

Do i have to properly pass the delete flag to it? If yes, how would i pass it in json?
I can't quite believe that i have to specify a new admin, because that would mean it is impossible to delete a group at all, since the last user could not name a new admin. So i think i am doing something wrong. Any help is apreciated!

That's a bug, I've created a issue for it.
