App deployment error - Building Boom package - HTTP 599: Timeout during request

I'm trying to deploy a shiny app to shinyapps.io. My first version of the app was successfully deployed here (https://mdeepm.shinyapps.io/northstar-new-user-activity/).

Now I've added some causal impact analysis to the app and I'm using the "CausalImpact" library to do this. The app builds and executes fine on my local machine. Following are the libraries that I'm using in my server.R file:

library(shiny)
library(ggplot2)
library(ggthemes)
library(plotly)
library(googlesheets)
library(scales)
library(dplyr)
library(reshape2)
library(hrbrthemes)
library(wesanderson)
library(xts)
library(CausalImpact)

But when I try to deploy it to shinyapps via rsconnect from RStudio, the building of Boom package takes very long and finally errors out (excerpt of the error given below).

I've searched for information on how to resolve this, but couldn't find any. Any help in pointing me in the right direction would be much appreciated!

having the same issue - did you have any luck fixing this? I believe its an issue with the Boom package

No, I couldn't find a way to fix this yet!
