Error post publishing RMD markdown app file

Hi all,

After publishing RMD file in Shinysapps.io, I am getting below error. May I know what could the issue?

Error : An error has occurred. Check your logs or contact the app author for clarification.

Hi we will need a little bit more information than that. You should be able to find the logs on your shinyapps.io account.

Is this a shiny runtime Rmd document that you are trying to publish ?
