Generate topography in Revit by Dynamo

Hi guys

I’ve been struggling to implement this tutorial from Timpothy Logan https://vimeo.com/143624038
What he suggests is bascally if the node cant read the tif file directly, you can check the info output and create a domain, based on the data there. The tif seems legit - 25mb, downloaded it from earthexplorer
So here’s what I get, but no result:


Any tips?
Thanks
