Cron job created from Cronr R package halting execution without error message to debug

I have a script written in R that collects data from a small group of APIs then writes collected data to a google drive account (using googledrive package).

This script runs without errors in RStudio and command line but, when I attempt to schedule the script to execute daily, I am having issues.

The job is created using the cronr add-in and acknowledges creation of the job:

Listening on http://127.0.0.1:6904
This is not a cron schedule but will launch: nohup /Library/Frameworks/R.framework/Resources/bin/Rscript '/Users/me/app_update_scripts/update_app.R'>> '/Users/me/app_update_scripts/update_app.log' 2>&1 &

So far, I have attempted giving the command sudo cron to make sure I have permissions.

I have directed the Cron job to output to the .log in an attempt to debug but I am given no error messages, just:
