I found the answer here -

> [@Set default value of a report's dataset parameter to empty](http://forum.inductiveautomation.com/t/set-default-value-of-a-reports-dataset-parameter-to-empty/11861/2):
>
> Try this expression:runScript('system.dataset.toDataSet([],[])')

However now I am not getting any errors and I still lack any preview
