Hi,
Few weeks ago I asked a question on how to get RICs for a given set of ISINs programmatically.
This was my question:-
API to get RICs for a given ISIN (Euro/UK Fixed Income Bonds) - LSEG Developer Community
So based on the answer I am using the dotnet samples given here
LSEG-API-Samples/Example.DataLibrary.DotNet: Example projects demonstrating access to the Refinitiv Data Platform using the Refinitiv Data Library for .NET.
Our firm has "Deployed Streaming" trep infra in our datacenter. So im trying to use that.
I am running the dotnet samples and using this specific code sample from the solution - "2.5.01-Symbology-Convert.cs". And trying to connect to our internal "Deployed Streaming".
It gets connected initially, the session is opened, but then when I make actual call of RIC conversion
SymbolConversion.Definition().Symbols("US5949181045", "US02079K1079")
.FromSymbolType(SymbolConversion.SymbolType.ISIN)
.ToSymbolType(SymbolConversion.SymbolType.RIC)
.GetData();
this call fails.
Below are the logs from the app:-

Failed to execute.
Exception: NotSupportedException Failed to execute GetDataAsync request. The session does not support data requests [/discovery/searchlight/v1/lookup]
Could someone please let me know what is the cause of this error? Do we need to allow some permissioning in our internal "deployed streaming infra" to make it work? Appreciate any help.ThanksSRQ
