Could not load data for the Visual in Power BI Service

In Power BI Service visual for one of my calculated column is not getting loaded. It is giving the following error:

"The query referenced calculated column 'RequestCountPerUser'[HourTime] which does not hold any data because evaluation of one of the rows caused an error."

Here, HourTime is the calculated column that basically calculate the Time from the TimeStamp column.

Note: The visual works in Power Bi desktop when Model is refreshed. The issue is pertinent only to the Power BI Service. Even in Power Bi Service the Visual works when the Model is published, the issue appears when the Model is refreshed.

Thanks!
