Environment

      "params" : {"var" : "hey there"}

    "message" : "This is a warning: %s",
    "params" : [ "warning" ]
  }
}

Actual Result

error: invalid type: map, expected a sequence at line 4 column 18

I made a mistake on this issue when i posted, but since then i've been using the official schema to validate my payloads, and i came across another error related to logentry, so i updated to reflect the new error i found.
