fix: Fixes uncaught errors in concurrency loop (#95)

# Description

Concurrency was added for parallel uploads which introduced a bug where
the try/catch wrapping this didn't properly catch the errors being
thrown from within the async functions.

This moves the try/catch inside of each upload process
