SVG files with Spark AR

I created a simple arrow SVG in Adobe Illustrator. When I tried to import into Spark AR, it says this error:

Does anyone know how to export an SVG from Illustrator in a way that will be accepted by Spark AR?

Try converting everything to fills. It should work for some things, but probably not filters, gradients, or patterns. Are you using any of those features it listed?

Oh thank you very much @josh_beckwith! I indeed had a stroke and didn’t register that in the error message. I changed it to fill only and now it works.
