Hi everyone!
I want a simple shiny app that allows the user to upload a pdf file and display it.
Locally, or when deployed to shinyapps io, everything seems to work fine.
But, on my server (linux machine) I get errors when uploading pdf files with no relevant error in the log.
for example, I used this app - How to upload and embed pdf in R shiny (iframe) · GitHub
works fine locally and on shinyapps io, but on my linux machine I get this error (attached image)
and this is the only text in the log file
"su: ignoring --preserve-environment, it's mutually exclusive with --login
Listening on ....... (here is IP)
"
when I checked a similar app with csv instead of pdf (code from file-upload html in shiny gallery - can't attach url) it works perfectly fine on the linux server.
I also checked an app with uploading functionality only, meaning no code in server side, only pdf fileinput in UI vs csv fileinput in UI, the first doesn't work (same error - 500 internal) while the latter works nicely.
any help would be very appreciated.
thanks alot!!
Tomer
