How to run ss-server without password?

[GermanAizek]

I configured iptables firewall to use port 1080 locally, tried to delete "password" string in config or set the value to null, nothing helped.

I tried:

{
    "server":["::1", "127.0.0.1"],
    "mode":"tcp_and_udp",
    "server_port":8388,
    "local_port":1080,
    "password":null,
    "timeout":86400,
    "method":null
}

and

{
    "server":["::1", "127.0.0.1"],
    "mode":"tcp_and_udp",
    "server_port":8388,
    "local_port":1080,
    "timeout":86400,
    "method":null
}

both configs not working.
