Adding an empty geojson source fails with unbound variable error

[sansumbrella]

When attempting to add an empty geojson source to my account, the cli crashes. I am attempting to upload an empty file so I can later copy data to my source from an S3 bucket.

tilesets add-source $USER $SOURCE tmp.geojson
