Error with sf package when uploading to

I've been working on an R shiny app that visualizes parking zones on a college campus using the sf and leaflet packages. Everything works fine locally, but when I try uploading the app to I recieve the following error:

I've tried updating / reinstalling the sf package, connecting to GitHub via devtools to access sf, and looked at similar troubleshooting problems but cannot find the solution. Any suggestions on how I might resolve my error will be greatly appreciated!
