问题 I'm trying to download a photo through a URL passed as a query string using Express, but every time I try to use it, I get Error: Invalid URI "favicon.ico" Is there a way I can get my browser to stop requesting a favicon?

问题 I have a React todo app I built using create-react-app and I built a simple express server to query mongoDB to get all the appointment objects.
