Just deployed an app to shinyapps.io and the app launches but greys out. The error I see in the log is pasted below related to "no package called data.table". The app runs fine locally and also runs fine with shiny server pro on system we have on premises.
I am not calling "data.table::" anywhere, but am using the function data.table() in many places (hundreds of places). The log doesn't give details enough to track down where the actual culprit is in code and my code is many thousands of lines. I can grep and see where data.table() is called throughout.
Below is a snippet from the log. Any advice for resolution?
