Escape characters inside my Post Body

[MarioKoestl]

Describe the bug

Function "Error()" of Serilog.ILogger is adding the \r\n escape characters to the string.

I am currently using the following Code to send a Log Message to an HTTP endpoint.

Serilog.Sinks 2.11.0
Serilog.SInks.Http 8.0.0

Adding Http Sink to LoggerConfiguration

  loggerConfiguration.WriteTo.Http(
                    restrictedToMinimumLevel: LogEventLevel.Information,
                    requestUri: "https://......",
                    httpClient: _serilogHttpClientFactory.Create(),
                    queueLimitBytes: null);

SerilogHttpClientFactory creates an Object of type "SerilogHttpClient"

SerilogHttpClient

public class SerilogHttpClient : IValue<System.Net.Http.HttpClient>, Serilog.SInks.Http.IHttpClient{
        public async Task<HttpResponseMessage> PostAsync(string requestUri, Stream contentStream)
        {
            using var content = new StreamContent(contentStream);

            content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
            var result = await Value.PostAsync(requestUri, content);
            return result;
        }
}

SerilogElasticExtender

public static class SerilogElasticExtender
 {
         public static void ErrorForElasticSearch(this Serilog.ILogger logger)
        {
            logger.Error("");
        }
}

To Reproduce

Call _integratorLogging.Value.ErrorForElasticSearch();

Expected behavior

I expect the following string to be sent to the endpoint:
"[{"Timestamp":"2022-08-01T09:31:19.8207278Z","Level":"Error","MessageTemplate":"","RenderedMessage":""}]"

But I found this string to be sent to the endpoint, which results in an error, because this string is no valid Json.

"[{"Timestamp":"2022-08-01T09:31:19.8207278Z","Level":"Error","MessageTemplate":"","RenderedMessage":""}\r\n]"

Additional context
The Real LoggingMessage was excluded in the given code snippets because the issue happens regardless of values.

Hi @MarioKoestl! Thanks for reporting the issue. As it currently is vacations here in Sweden work is slow. I'll make sure to investigate you issue when I return from my time spent in the sun.

Hi @MarioKoestl.

I've been trying to reproduce your issue. In repository FantasticFiasco/serilog-sinks-http-sample-dotnet-core I've created a branch named issue-268 which seems to use the same code as you've shown here, although this code doesn't reproduce your issue. Would you be able to clone this repository and update it to showcase your problem?
