Elasticsearch 7 default mapping deprecated and no longer supported

[samcro1967]

I updated to the latest version of the docker container sebp/elk on 4/17/2019. Since then I have been unable to get Telegraf to start on my host. It fails connecting to Elasticsearch. I also get a 502 error connecting to Elasticsearch from Grafana. I have removed all containers and images and re-pulled. I also deleted all data in mount points to start clean and still am unable to connect. The only change I am aware of that was made on 4/17/2019 was the upgrade of sebp/elk.

Here is the link I got from the Elasticsearch forum to its deprecation announcement"
https://www.elastic.co/guide/en/elasticsearch/reference/current/breaking-changes-7.0.html#_the_literal__default__literal_mapping_is_no_longer_allowed

I am running the following versions:
Grafana 6.1.4 (docker container)
Elasticsearch 7.0.0
Telegraf is 1.10.3 (runs locally on host)
InfluxDB 1.7.6 (runs locally on host)
Docker 18.09.2
Windows 10.0.17763.437

From http://localhost:9200 I get
