IMultisearchResponse's ConnectionStatus.Request is null

[philbarresi]

I am trying to log the requests I am making to better debug some internal issues, and apparently after performing an var results = await _client.MultiSearchAsync(...), sometimes results.ConnectionStatus.Request comes back as null. I am attempting to get the JSON request that hits the server; if there's a better way to do that, I would love to know.

Hi @xueye this is definitely a bug.

I have a hard time reproducing it can you share a little bit more of the code that you have in place?

How does _client get constructed (what settings? connectionpooling? different connection?)

Hi there! It's very hard to reproduce; my theory is that this happens when there would be an XContent exception thrown.

This function generates the settings we use.

            public static ConnectionSettings BuildSettings(params Uri[] uris)
            {
            var pool = new SniffingConnectionPool(uris, randomizeOnStartup: true);

            var settings = new ConnectionSettings(pool);
            settings.SniffOnStartup(true)
                .SniffLifeSpan(TimeSpan.FromSeconds(5));
            settings.SetPingTimeout(1000);
            settings.MaximumRetries(10);

            settings.MapDefaultTypeNames(x => x.Add(typeof(CompanyProfile), CompanyProfileType)
                .Add(typeof(PersonProfile), PersonProfileType)
                .Add(typeof(FeedItem), FeedType));

            settings.MapDefaultTypeIndices(x => x.Add(typeof(CompanyProfile), CompanyIndex)
                .Add(typeof(PersonProfile), PeopleIndexName));

            settings.DisableAutomaticProxyDetection(false);

            settings.SetJsonSerializerSettingsModifier(serializer =>
            {
                var mappings = new FluentMappings(wrappedResolver: serializer.ContractResolver);
                mappings.MapClass<CompanyProfile>(cm =>
                {
                    cm.MapMember(x => x.Domains, x => x.SetConverter(new WheeConverter()));
                });

                mappings.MapClass<InvestmentEntry>(cm =>
                {
                    cm.SetDiscriminator("InvestmentEntry");
                });

                mappings.MapClass<CorporateInvestmentEntry>(cm =>
                {
                    cm.SetDiscriminator("CorporateInvestmentEntry");
                });

                mappings.MapClass<IndividualInvestmentEntry>(cm =>
                {
                    cm.SetDiscriminator("IndividualInvestmentEntry");
                });

                serializer.ContractResolver = mappings.ContractResolver;
                serializer.Binder = mappings.Binder;

                serializer.Converters = serializer.Converters ?? new List<JsonConverter>();
                serializer.Converters.Add(new StringEnumConverter());
                serializer.Converters.Add(new StringProviderIdentifierConverter());
                serializer.Converters.Add(new LanguageInfoConverter());
            });

            settings.SetTimeout((int)TimeSpan.FromSeconds(60).TotalMilliseconds);

            return settings;
            }

This is happening a few times every day, and I managed to get a bit more info. This happens whenever there is a Failed to derive xcontent from org.elasticsearch.common.bytes.BytesArray@1 issue (which is what I was originally trying to debug). Is there any other way to get a string of the JSON request before I actually await the call so I can try and see what's causing the xcontent issue?

@xueye I have not been able to reproduce this, will close this for now but please report back if you still seeing this issue!
