Hi all,

my shiny app is running locally, but when I'm trying to deploy it to shinyapps using rsconnect deployApp(), it published but getting an error message like this in the logs:

-------- in shinyapps log--------
Error in file(file, "rt") : cannot open the connection
Calls: local ... tryCatch -> tryCatchList -> tryCatchOne ->
Execution halted

and

Warning in file(file, "rt") :
cannot open file '(my file pathway)': No such file or directory
Error in file(file, "rt") : cannot open the connection
Calls: local ... tryCatch -> tryCatchList -> tryCatchOne ->
Execution halted

what is this ?
You may need to reconsider how you structure your app and refer to paths; you should adopt an approach based on relative paths; as when you deploy to a server (another machine) it will put you into a filespace that you cant predict the exact location of, all that you can know is that your main folder will be placed somewhere, and its subfolders will be within it.
