I'm relatively new to using R and shiny. Currently, I'm getting the Error:
Conflict (HTTP 409) when trying to access an html file from dropbox and
this is fine, I know the reason. What I do have a problem with is trying to
find a way to change Error code message. Instead of simply "Error: Conflict
(HTTP 409)", I would a message a client might be able to understand. I've
tried a couple forms of validation and try-catches. I'm including the code
and simple html files to recreate the problem. Any and all suggestions are
welcome. Thank you in advance for your help.
