I am testing on the Shiny 1.5.0.9xxx version from github. I noticed the original error traceback is gone. Only a very simple message:
Warning: Error in exists: invalid first argument
1: runApp
In < v1.5
Warning: Error in exists: invalid first argument
82: exists
81: self$exists
80: oldInputs$available
79: restoreInput
78: selectInput
73: selectizeInput
72: observeEventHandler [R/xxx.R#323]
1: runApp
I tried with new devmode()
function but still the same. The only way I know right now is options(shiny.fullstacktrace = TRUE)
. Is there any new config that I'm missing in the new version?
Thanks, this is a regression. Can you file an issue at: https://github.com/rstudio/shiny/issues

It seems today's new version brings the trace back ( 1.6.0.9000)
Hi @lz100 , any chance you can provide us with a reproducible example?

I am using 1.6.09, seems the tracing is back.
library(shiny)
funcA <- function(){stop("a")}
funcB <- function(){funcA()}
ui <- fluidPage()
server <- function(input, output, session) {funcB()}
shinyApp(ui, server)
results
Listening on http://127.0.0.1:5742

52: stop

50: funcB [#1]
