So dep isn't available anymore and has been deprecated since 2020 which makes testing very hard. I've updated to go mod. This PR also fixes the above error. Conversions should handle the possible failure case and now it does. Hopefully that makes sense. I need this for a work project so I hoping we can get this worked out. Thanks!
