Upgrade to es 6.1.0 trouble

Elastic Stack Elasticsearch
7

Hi,

I am still struggeling.
I have a new index for each type but I get the following error:

14:20:21.483 [Ruby-0-Thread-40@[main]>worker0: /usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:392] WARN logstash.outputs.elasticsearch - Could not index event to Elasticsearch. {:status=>400, :action=>["index", {:_id=>nil, :_index=>"events-state-2017.12.19", :_type=>"doc", :_routing=>nil}, #LogStash::Event:0x7b701c76], :response=>{"index"=>{"_index"=>"events-state-2017.12.19", "_type"=>"doc", "_id"=>"8mclb2ABzTth-5wZkhFh", "status"=>400, "error"=>{"type"=>"illegal_argument_exception", "reason"=>"Rejecting mapping update to [events-state-2017.12.19] as the final mapping would have more than 1 type: [doc, state]"}}}}

Then I found this:
https://discuss.elastic.co/t/rejecting-mapping-update-for-new-index/109576

Does it mean that I should not use templates at all in ES6?
(I though templates are required to get correct types)

I have the following template for state.

{
    "template": "events-state-*",
    "id": "events-state-*",
    "type": "index-pattern",
    "version": 1,
    "mappings": {
        "state": {
            "dynamic_templates": [

.
.
.

Can you explain how the template should be written?

Kind regards
Mathias
