Hi @anass.yazane.1

Can you confirm which version of the Refinitiv NuGet library you are using? The latest version is 1.0.0-beta4.

In general, the library will pass through the requested item name(s) directly to the backend service which will handle proper validation. The library typically does not override validation before the request is sent down, but instead relies on the backend. This is generally done across all services.

In my first test against the platform session, when I performed the exact request you did, the request works and a status message is sent back from the server indicating the request Key did not contain a name.

 {
  "ID": 2,
  "Type": "Status",
  "Key": {
    "Service": "ELEKTRON_DD"
  },
  "State": {
    "Stream": "Closed",
    "Data": "Suspect",
    "Code": "AlreadyOpen",
    "Text": "Request Rejected: Request key did not contain name."
  }
}

However, when I test against a 'desktop' session, the request does not complete because the backend service did not provide the expected 'Status' message. As a result, the call to GetStream() does not return/complete. In addition, I did not receive any Exception nor did the application crash.

If you are using the latest version of the NuGet package, can you confirm the Platform session reacts the same as the Desktop session - it is not for me. And also provide more details around the crash, i.e. Exception details.
