Failed to parse mapping to Elasticsearch on ES8.1.0

[BinGuoGuo]

Hi，when I run docker-compose up -d, I got these information. My Elasticsearch image version is elastic/elasticsearch:8.1.0 and I've config a superuser for docker-compose.yml

I've install mapper-size plugin on my ES, but it still not work :(

We currently only support ES 7.x, We'll bump the Exceptionless major when we support ES 8.
