Refinitiv Data Library .Net do not work under linux

bmirzai

If I run the following code in Windows

Log.Level = NLog.LogLevel.Debug;
Log.Output = (loginfo, parms) => Console.WriteLine($"Application: {loginfo.Level} - {loginfo.FormattedMessage}");
var response = await Search.Definition().View(Search.LightView.SearchAllLight).Query("apple").Select("RIC")
                .Top(10).GetDataAsync(session);

Everything work fine and debug message in console is

Application: Debug - Preparing Endpoint POST request https://api.refinitiv.com/discovery/searchlight/v1/ with Content:
"{
  "View": "SearchAllLight",
  "Query": "apple",
  "Select": "RIC",
  "Top": 10
}"

But if the code is running in a Docker container on Linux (WSL or bare metal server) the code will fail with an error

System.NotSupportedException: 'The 'file' scheme is not supported.'
   at System.Net.Http.HttpClient.<SendAsync>g__Core|83_0(HttpRequestMessage request, HttpCompletionOption completionOption, CancellationTokenSource cts, Boolean disposeCts, CancellationTokenSource pendingRequestsCts, CancellationToken originalCancellationToken)

   at RefinitivBug.Program.Main(String[] args) in E:\Work\RefinitivBug\RefinitivBug\Program.cs:line 29

And debug message in console is

Application: Debug - Preparing Endpoint POST request file:///discovery/searchlight/v1/ with Content:
"{
  "View": "SearchAllLight",
  "Query": "apple",
  "Select": "RIC",
  "Top": 10
}"

Is there a workaround or quick fix for this?

Hi @bmirzai

I recall this same issue reported by another client last year related to the root part of the URL and how Linux evaluates the structure differently on Windows. The .Net call seems to convert the request to look like: file:///data/...

This should be resolved in the next release of the library coming out later in June.

There is a workaround that you can try. I've attached a configuration file that overrides this specific URL. You can place this config file (refinitiv-data.config.json - you will need to rename the file to remove the .txt extension) within the root directory of your project and ensure after your build, this file will be copied to your runtime (bin) dir which is one of the places the lib will search for it.

Thanks.
