Exception thrown when trying to use Elasticsearch output

I’m seeing the following exception thrown when trying to use the Elasticsearch output package. I’m using the following EventFlow packages:

Microsoft.Diagnostics.EventFlow.Inputs.EventSource 1.4.6 Microsoft.Diagnostics.EventFlow.Outputs.ElasticSearch 2.7.2 Microsoft.Diagnostics.EventFlow.ServiceFabric 1.6.0

Here’s my eventFlowConfig.json:

{
	"inputs": [
		{
			"type": "EventSource",
			"sources": [
				{ "providerName": "Microsoft-ServiceFabric" },
				{ "providerName": "Microsoft-ServiceFabric-Services" },
				{ "providerName": "Microsoft-ServiceFabric-Actors" },
				{ "providerName": "MyApp-MyService" }
			]
		}
	],
	"outputs": [
		{
			"type": "ElasticSearch",
			"indexNamePrefix": "myApp",
			"serviceUri": "https://<deploymentId>.eastus2.azure.elastic-cloud.com:<port>",
			"basicAuthenticationUserName": "<user>",
			"basicAuthenticationUserPassword": "<password>",
			"refreshInterval": "15s",
			"mappings": {
				"properties": {
					"timestamp": {
						"type": "date_nanos"
					}
				}
			}
		}
	],
	"schemaVersion":  "2016-08-11" 
}

At my program’s entry point, I set it up with:

private static void Main() 
{
  try
  {
    using diagnosticsPipeline = ServiceFabricDiagnosticPipelineFactory.CreatePipeline("myPipeline");

And that should be about all of it. When I start the program, I receive the following exception in the catch block:

System.Exception: 'DiagnosticPipelineFactory: item of type 'ElasticSearch' could not be created
System.TypeLoadException: Could not load type 'Elasticsearch.Net.IInternalSerializerWithFormatter' from assembly 'Elasticsearch.Net, Version=7.0.0.0, Culture=neutral, PublicKeyToken=96c599bbe3e70f5d'.

I tried installing Elasticsearch.Net 7.8.1 in hopes that the most recent version would fix things, but the issue persists.

Any ideas of what I’m doing wrong in hooking this up?

Thanks!

Sure - give me a few to put something together.

That fixes it on my side. Thank you for your assistance here!
