Hey @ehubbell. Happy to know that you solved your issue!
I will say, FA’s documentation around all this was pretty non-existent. It would help if you specify in the docs that the file picker uploads a base64 encoded string that you can then write to the filesystem server-side. That should help any future developer get on the right track.
We’re always looking for this kind of feedback. I’m forwarding this to the team so the documentation can be updated that way.
Thanks
