I am working on a dashboard, where in backend Kusto query are running and plot a graph on dashboard based on the results.
I am trying to print a custom message like,
| extend CustomColumn=iff(isempty(expectedExpiration),"Expiration data is not available for this ",expectedExpiration)
i tried isempty, isnull, isNaN function as well but I am not getting this custom message as an output.
Can you help in finding what is going wrong here or I am missing something?
