Template issue

[tgdesrochers (Tim Desrochers)]

I am having some issues with my elastic template. When I added the IP fields I receive errors. If I remove them it works fine. Can someone shed light on what I am doing wrong.

I took the default template for logstash and edited it to create the one below. I am in no way a template guru.

Elasticsearch 5.4
Logstash 5.4

Error:
