kibana basic的用法

想要通过basic的方式来使用kibana，发现如下问题：
 
配置如下：

server.port: 5601

server.host: "xx.xx.xx.xx"

elasticsearch.hosts: ["https://xx.xx.xx.xx:xxxx"]

elasticsearch.username: "xxxx"

elasticsearch.password: "xxxx"

#server.ssl.enabled: false

elasticsearch.ssl.verificationMode: none

elasticsearch.customHeaders: {"customHeader":"Zxxxxxxxx"}

logging.dest: /opt/install/kibana.log

elasticsearch.healthCheck.delay: 600000

 
1. basic方式登录正常
2. devTools可以正常使用（通过自定义Header 构造Basic标识信息来实现）
3. create index partten 报500异常
 


 
如何能使create index partten 正常使用？
 
 
日志如下：
