I am trying to publish the app shiny. But the problem is that the output is an error: "An error has occurred. The application failed to start. Contact the author for more information".
In my script the database is upload from server amazon using mysql. My script is clean, funcional and it working localy at the moment.
I am connected using a code. This picture is just one piece the code.
Thank you for your answers.
Regards,
M.
