My dashboard has been working fine for weeks. then I all of sudden i start getting the error message below

The error occurs at the Renamed Column3 step. Does anyone know why it is occuring and how to resolve it?

Hi @dw700d 

In this case, the data source has changed and the column in the /query request has disappeared or its name has changed.

Either you need to correct the data source or delete/redo the step.
