Autogreate template failes

Trying to use the elastic sink. It works for a short time, then failes...

This is my setup :

return m_LoggerConfiguration.WriteTo.Elasticsearch(new ElasticsearchSinkOptions(new Uri(TmpURL))
{
AutoRegisterTemplate
= true ,

            AutoRegisterTemplateVersion
                = AutoRegisterTemplateVersion.ESv6,

            CustomFormatter
                = new ElasticsearchJsonFormatter(false , null , true , null , null , true , false, false) ,
        });

This is the error 👍

Any idea what's going on ?

Hard to see why it is rejecting this. Can you see from the ES logs why it is returning a 400?

I have a similar issue, I'm using Elasticsearch 7.8.0 on Docker (Linux) and the sink on NetCore3.1 and get the following error:

Request failed to execute. Call: Status code 400 from: PUT /_template/serilog-events-template.

In my case, it helps to set AutoRegisterTemplate to false, however...

I will try to get the database log as well.

I fixed this using AutoRegisterTemplateVersion = AutoRegisterTemplateVersion.ESv7.
