Hi Thomas!
Well good you are getting that, means lodash is coming through properly.
Now for your issue. I went back to the post on visulations that we initially did this on, and I see I made a mistake that I forgot to correct in there.
var portfolios = obj.portfolios is wrong
it shoud be portfolios = obj.report.portfolios
When I did that, I got a result and you should too.
Let me know if that fixes it!
Regards,
