Kibana enable cors

Elastic Stack Kibana

I was able to start kibana locally from source code (this time on windows). With setting server.cors.origin I get same error (last time I got same error on unix)

$ sh ./bin/kibana
FATAL { ValidationError: child "server" fails because [child "cors" fails because ["cors" must be a boolean]]

  isJoi: true,

  details:
   [ { message: '"cors" must be a boolean',
       path: 'server.cors',
       type: 'boolean.base',
       context: [Object] } ],
  _object:
   { pkg:
      { version: '5.6.8',
        branch: '5.6',

     dev: { basePathProxyTarget: 5603 },
     pid: { exclusive: false },
     cpu: undefined,
     cpuacct: undefined,
     server: { cors: [Object] } },
  annotate: [Function] }

I think if I start kibana like this $ sh ./bin/kibana it starts in prod mode
