deoplete-ternjs: Doesn't seem to work

Running latest deoplete and deoplete-ternjs, I get this when autocompletion starts:

Tern is installed globally:

└── tern@0.17.0

This is my tern config:

{
  "libs": [ "browser", "ecma6", "ecma5" ],
  "loadEagerly": [],
  "dontLoad": ["node_modules"],
  "plugins": {
    "complete_strings": true,
    "doc_comment": true,
    "modules": true,
    "node": true,
    "node_require": true
  }
}

Any ideas?
