Hi all,

When i try to use group by aggregation getting this error.


Is there anyone know how can i fix it?

please tell us where you found this activity since it is not an official one…

Group By Aggregation? No it has in uipath for very long time.


But can you say which package?

I believe its BalaReva.DataTable.Activities
Its very handy package. You guys should include him.

Should be naming issue only,after switch to SubmittedAmt,it works fine.
