This issue only occurs in R Studio Connect server. It works well in my local system though.

Development:

Set up renv environment

# Initialize a empty renv environment
renv::init(bare = TRUE)
# Install radiant: this step also installs all packages mentioned in radiant/inst/app/for.shinyapps.io.R
renv::install(c("rsconnect", "radiant"))
# Save environment
renv::snapshot()

Create app files:

server.R

server_path <- system.file("app", "server.R", package="radiant")
source(server_path)

ui.R

ui_path <- system.file("app", "ui.R", package="radiant")
source(ui_path)

global.R

library(radiant)
global_path <- system.file("app", "global.R", package="radiant")
source(global_path)

Edit .Rprofile

source("renv/activate.R")
# Source https://radiant-rstats.github.io/docs/
options(radiant.maxRequestSize = -1)  ## no file size limit
options(radiant.report = TRUE)

Deployment

Create manifest.json file for R Studio Connect

This is completed inside the renv environment.

rsconnect::writeManifest()

Publish code to GitLab

Git stage, commit and push to GitLab

Deploy in R Studio Connect from GitLab

Deploy app from GitLab to R Studio Connect (Not using "publish" button in R Studio IDE).

Deployment log from R Studio Connect:

I'm afraid I don't use Rstudio Connect at all (yet). Don't know how to help you with this one I'm afraid.

[vnijs]

Please let me know if you were able to get this working with RStudio Connect.

[DSChip]

I was not able to solve this issue myself. I have not tried again since this ticket was created.

[vnijs]

The app runs on ShinyApps.io which, I believe, uses Rstudio Connect. It should be possible to run the app on connect. That said, I haven't tried it. Do you have a acces to shinyServer?

[DSChip]

Do you have a acces to shinyServer?

AFAIK, ShinyServer has been completely replaced by R Studio Connect. I do have access to R Studio Connect though.

[vnijs]

Do you mean, in your organization? From the below rstudio still offers and sells Shiny Server

[DSChip]

Yes, our organization has R Studio Connect. Sorry, I was not aware that Shiny Server was still available.
