Steps to replicate

I'm using this Dockerfile:
FROM fluent/fluentd:edge-debian

USER root
RUN ["gem", "install", "fluent-plugin-aws-elasticsearch-service"]
RUN ["gem", "install", "fluent-plugin-record-modifier"]
RUN ["gem", "install", "fluent-plugin-http-healthcheck"]
RUN ["apt-get", "update"]
RUN ["apt-get", "-y", "install", "curl"]

HEALTHCHECK --interval=30s --timeout=3s CMD curl -v http://localhost:8888 || exit 1

COPY entrypoint.sh /bin/

USER fluent

Provide example config and message

<match gelf-logging>
  @type "aws-elasticsearch-service"
  type_name "access_log"
  logstash_format true
  include_tag_key true
  tag_key "@log_name"
  logstash_prefix dummy
  templates { "dummy": "/fluentd/etc/dummy.json" }
  flush_interval 10s

  <endpoint>
    url "https://myElasticSearchInAws.eu-central-1.es.amazonaws.com"
    region "eu-central-1"
  </endpoint>
</match>

Same issue here. Started to happen friday. There is no new version of the ES plugin so i don't why it started to happen out of the blue like that.
