I've tried to use the api HistoricalChainResolution and after that i create a list identifer, but i get validation error like:



"RIC, ADSSH0 (not found)"



below the test code:




  var search = ContextHelper.CreateSearchContext();
            var extractionsContext = ContextHelper.CreateExtractionsContext();
            var request = new HistoricalChainResolutionRequest();
            request.ChainRics = new ThomsonReuters.Dss.Core.RestApi.DssCollection<string>("0#ADSS:");
            request.Range = new DateTimeRange();
            request.Range.Start = new DateTimeOffset(1996, 01, 01, 00, 00, 00, TimeSpan.Zero);
            request.Range.End = DateTimeOffset.UtcNow;

            var chainResolution = await search.HistoricalChainResolutionAsync(request);

            await extractionsContext.InstrumentListOperationsAsync.CreateAsync(new InstrumentList()
            {
                Name = "Test"
            });

            var appendResult = await extractionsContext.InstrumentListOperationsAsync.AppendIdentifiersAsync(
                 await extractionsContext.InstrumentListOperationsAsync.GetByNameAsync("Test"),
                chainResolution.SelectMany(i => i.Constituents).Select(c => InstrumentIdentifier.Create(c.IdentifierType, c.Identifier)),
                false
                );
