Bug: Function Exists but Returns "Not Defined" in Kusto Extension for Azure Data Studio

[asilverman]

Type: Bug

Description:

I encountered an issue in the Kusto extension for Azure Data Studio where a function that clearly exists in the database (GetScanners) is still reported as "not defined." This error is inconsistent with the list of available functions displayed in the object explorer.

Steps to Reproduce:

1. Open Azure Data Studio with the Kusto extension installed.
2. Connect to a Kusto cluster and database.
3. Verify that the database defines a function (like GetScanners as shown in the screenshot below) under the "Functions" node in the database structure.
4. Run a query to get data from that function (as shown in the example below):

  cluster('shiftleft-uw-prod.westus').database('shiftleftdb').GetScanners()

5. Observe the error:

   The function 'GetScanners' is not defined.
