Hi,
I'm getting the "dot not allowed in field name" exception, on a 5.5 cluster on AWS (elasticsearch service), the odd thing is that this doesn't happen on my local ES running on a docker container, I'd assume this is a configuration issue on AWS side, I read everywhere that [dots in field names are allowed in 5.x](https://www.elastic.co/guide/en/elasticsearch/reference/2.4/dots-in-names.html) so I'm confused on what is triggering this behaviour and if there's a way to debug this

What request are you making? At a quick glance, I don't see that error message in the 5.x codebase.
