Traefik cannot read constraints from KV

[altvnk]

I'm running Traefik v1.1.0-rc3 (Darwin) with Consul KV configuration loading.
When i'm setting traefik/consulcatalog/constraints or traefik/constraints to ["tag==exposed"] Traefik returns me an error:

./traefik --consul --consul.endpoint=127.0.0.1:8500
2016/11/02 00:16:56 Error loading configuration: 1 error(s) decoding:

* illegal base64 data at input byte 0

I've tried to encode it into Base64... Didn't helped:

./traefik --consul --consul.endpoint=127.0.0.1:8500
2016/11/02 00:16:13 Error loading configuration: 18 error(s) decoding:

Fixed in #814

Sorry for bringing this up again, but i'm still not able to run Traefik with constraints in KV...
In which format should i store the constraints in KV?

Here's what i currently have:

http http://consul.service.consul:8500/v1/kv/traefik/consulcatalog/constraints
HTTP/1.1 200 OK
Content-Length: 148
Content-Type: application/json

        "Flags": 0,
        "Key": "traefik/consulcatalog/constraints",
        "LockIndex": 0,
        "ModifyIndex": 5460034,
        "Value": "WyJ0YWc9PWV4dGVybmFsIl0="
    }
]

echo "WyJ0YWc9PWV4dGVybmFsIl0=" | base64 --decode
["tag==external"]

But latest release i've just downloaded gives me this:

2016/11/10 22:55:01 Error loading configuration: 1 error(s) decoding:

* illegal base64 data at input byte 0

Wondering if i'm doing something wrong here...

@altvnk I suggest to build your configuration in a TOML file, and then use traefik storeconfig to upload it in your KV store.
