Export Areas to SVG, Power BI, Warning: PolyCurve.ByJoinedCurves operation failed

I am attempting to convert area boundaries to an SVG file for use in Power BI. Following ABG’s tut: Revit plans to Power BI using Dynamo! (Part 2 of 2) - YouTube

It works fine when I do this workflow with Rooms, but when I try to change it to be Areas, I get an error: “Warning: PolyCurve.ByJoinedCurves operation failed. Curve join produced more than one WIRE in PolyCurve”. Now the SVG does export, but it doesn’t link to the data in Power BI. I suspect it’s because of this error. Any thoughts here?

Or thoughts on a workaround to convert the Area boundaries to Room Boundaries.

What it looks like in Power BI:
