Filebeat having error in bulk index operations

[rich456 (Rich)]

Hi all,

I just started exploring ELK stack for my company and I am quite new to this. I am encountering an error, and this is the error logs:

I am trying to send logs from a server using filebeat to the ELK stack server installed with kibana and elasticsearch. I am not sure what wrong with it. Can anybody help me with this?

P.S. I did a lot of search on the error, but I could not find a solution.

OS version: CentOS 7.5
filebeat version: filebeat version 1.3.1 (amd64)

OS version: CentOS 7.5
kibana version: 6.3
elasticsearch version: 6.3

You should really use version 6.3 of Filebeat as well, so it matches the rest of the stack. Version 1.x of Beats are not compatible with version 6.x of the stack.
