Serilog.Sinks.Http 8.0.0 does not seem to work with Serilog.AspNetCore 6.0.1

[hoaol]

Hi! I have a .NET 6 ASP application where I have updated the Serilog.AspNetCore package to 6.0.1 and at the same time also upgraded Serilog.Sinks.Http to 8.0.0. After that the logging to elastic stopped working (we can still log to file and console). If I revert to 7.2.0 it works again. We are configuring the sink via appsettings.json:

{
                "MinimumLevel": "Debug",
                "Name": "Http",
                "Args": {
                    "requestUri": "http://myElasticServer:9606/",
                    "queueLimitBytes": null
                }
}

I have checked the list of breaking changes but do not anything applies to our usage.
Does anyone have an idea what could cause this problem? Right now it is no problem for me to keep using 7.2.0 but in the long term I would like to "upgrade".

Kind regards Hans

Hi @hoaol!

It's currently summer vacations here in Sweden now. I'll look at your issue when I return.

Hi @hoaol. Is this still a problem?

We can use the 7.2.0 version for now and if nobody else ha reported anything similar to this I suppose we can wait until we need to step up to a 8.* version and maybe do some more investigation. I suppose the problem could be in Serilog.AspNetCore as well (or in our application)

We have now encountered the same problem in another project, would it be easy for you to verify that Serilog.Sinks.Http 8.0.0 works with Serilog.AspNetCore 6.0.1 (maybe that has already been done)?

Do you think that there were any changes made in 8.0.0 that would require us to change how we use it?

I just wanted to mention that I have now resolved this, I had missed that the format for "batched" log events had changes (there is no longer an events property with the log items) and we had a logstash "transformation" on the logs (that I had fogotten about) that depended on the old "batch" format

Version 8.0.0 or later

    /// <summary>
    /// Formatter serializing batches of log events into a JSON array.
    /// <para/>
    /// Example:
    /// [
    ///   { event n },
    ///   { event n+1 }
    /// ]
    /// </summary>
    public class ArrayBatchFormatter : IBatchFormatter

Version 7.2.0

    /// <summary>
    /// Formatter serializing batches of log events into a JSON object under a property called "events".
    /// <para/>
    /// Example:
    /// {
    ///   "events": [
    ///     { event n },
    ///     { event n+1 }
    ///   ]
    /// }
    /// </summary>
    public class DefaultBatchFormatter : BatchFormatter
