Publishing app to shiny apps.io

I have three excel databases that I'm pulling into my code (I cannot share any data due to the privacy rules of my organization- I understand that this is an issue).

My app runs perfectly fine and shows me what I want to see. The only issue I have is when I publish- it is connected to my account, and my logs seem to show no errors:
