Shiny app works fine locally, but error when publishing to Shiny server

My application worked perfectly locally and on Shiny server.

After including two new libraries, my application stopped working on Shiny server, but works perfectly locally.

library (geojsonio)
library (broom)

When I upload my changes to Shiny server I get the following error:

Preparing to deploy document...DONE
Uploading bundle for document: 3086934...Warning in FUN(X[[i]], ...) :

The libraries that I load at the beginning of my script are the following:

library(dplyr)
library(ggplot2)
library(formattable)
library(geojsonio)
library(broom)

The 'foreign' library seems installed.

I hope someone knows how to help me. Forgive my english. Thanks in advance.

Would you consider upgrading to a more recent version of R, and updating your packages to the later version ?

Thanks a lot!

It works now. It was silly but I had been looking for the mistake for days. Thanks again.

Did upgrading to R4.0 resolve your issue?

yes i updated, it asked me to reinstall some packages and it worked perfectly.
