Hi all,

I have made a custom plugin for kibana version 6.2.1, in which I am having a form, now whenever I am submitting those form values with get request all works absolutely fine.

But submitting the form values with a post request I always get the below mentioned response error.

{"statusCode":400,"error":"Bad Request","message":"Request must contain a kbn-xsrf header."}

kindly help me resolve this error for my post request.

I am using windows OS and kibana version 6.2.1

Any help will be greatly appreciated.

Thanks in advance.

Hi,

Kibana expects the header 'kbn-version' to be passed on requests, it's used to protect against xsrf attacks.  
for ex:  
`adding -H kbn-version:x.x.x` should get around that error.  
Try it out and let us know

Cheers  
Rashmi
