Read sometime fails

[Kanshiroron]

Hello,

I've been using this adapter to send and read collected metrics from ElasticSearch. I was creating some Grafana Dashboard when I noticed that some queries/graph were not working properly, and the adapter throws a stacktrace:

Best,

[pwillie]

This actually looks like an error on write. What version are you using?

[Kanshiroron]

Hey @pwillie,
I was using the docker 'latest' version so it should be the last image before the version 6 you released some days ago.
Best regards
