Seeing metadata error when subscribing to streaming summaries for specific instruments

cory.schmidt.1

In the HistoricalPricing - TSInterday project we're subscribing to streaming summaries with a Daily interval and are receiving the following error: "Error: Failed to load meta data. Failed to load Instrument Metadata for item: AUA04000524=WPAC". The same error is returned for US1DCP=. Here is the code that can duplicate the problem...

    // Create the platform session.
    using ISession session = Sessions.GetSession();

    // Open the session
    session.Open();

    var stream = Summaries.Definition("AUA04000524=WPAC")
        .Interval(Summaries.Interval.P1D)
        .GetStream();

    // Specify the TSI lambda expressions to capture 'Insert' and 'Update' events
    stream.OnInsert((data, stream) => Common.DisplayTable($"INSERT: {DateTime.Now}", data.Table))
          .OnUpdate((data, stream) => Common.DisplayTable($"UPDATE: {DateTime.Now}", data.Table))
          .OnStatus((status, stream) => Console.WriteLine($"Status: {status}"))
          .OnError((error, stream) => Console.WriteLine($"Error: {error}"))
          .Open();

    Console.ReadLine();
}
catch (Exception e)
{
    Console.WriteLine($"\n**************\nFailed to execute: {e.Message}\n{e.InnerException}\n***************");
}

Hi @cory.schmidt.1

Based on my initial investigation, there doesn't appear to be any metadata associated with the instruments you highlighted. The library is simply reacting and reporting it is unable proceed because metadata rules are at the heart of the processing.

We'll need to follow-up with the server team to report this issue. You did note 2 instruments, if you have any others, please share and we'll provide the team these details.

thanks.

Hello @cory.schmidt.1

The error seems to be caused by a parsing issue of the incoming response for the instruments used in the example. Could you please provide any generated logs ?

Thanks,

Cristian

I can replicate this error.

The debug log looks like this:

@Jirapongse

Thank you for the help !

@cory.schmidt.1

By looking at the logs it seems that the incoming object is empty.

I will start my investigation into this issue.

@cory.schmidt.1

My initial observation that the incoming response is empty was correct.

It seems that the endpoint is responding with a 200 (OK) http status code, but there is no content for us to parse.

Continuing investigation...

@cory.schmidt.1

It seems that retrieving summary data (not streaming) works, using a simple endpoint definition, like this:

var universe = "AUA04000524=WPAC";
var url = "https://api.refinitiv.com/data/historical-pricing/v1/views/interday-summaries";
var endpoint = $"{url}/{universe}";

var response = EndpointRequest
    .Definition(endpoint)
    .QueryParameter("interval", "P1D")
    .GetData();

I will continue investigating to see why there is no data for streaming...

What I found so far is that instrument metadata is the object not retrieved for AUA04000524=WPAC , but I haven't found the reason why yet. I am using the exact same example code and replacing the faulty instrument with EUR= and I have no issues...

Instrument metadata is something we cannot ignore as being null or empty because it is used in streaming for normalization of incoming records based on data filter clauses and rules in order to obtain correct data.

There are also no errors, warnings or other information coming back with the response.

I will probably need to discuss with @nick.zincone about this issue next week to gain more knowledge...

Hi @cory.schmidt.1

Should you require a content enhancement, you just need to raise a support ticket via my.refinitiv site the same way you raise support tickets for any other product/content concerns and once support receives it they'll go through the process from there.

Thanks, I'll get that raised today.
