any help please

There error is something to do with paths.
Make sure you are not using absolute file paths or setwd or getwd.
Make sure you are uploading only the files your app needs.

Does your application work when you run it locally?

@josh yes sir it works perfect on local host, bear in mind, the whole app built on rstudio cloud.,
I really don't understand this
Warning: Error in value[[3L]]: Couldn't normalize path in addResourcePath , with arguments: prefix = 'AdminLTE-2.0.6'; directoryPath = '/home/rstudio-user/R/x86_64-pc-linux-gnu-library/3.6/shinydashboard/AdminLTE'

no setwd or getwd
the whole app was built on rstudio cloud
the error is this
Warning: Error in value[[3L]]: Couldn't normalize path in addResourcePath , with arguments: prefix = 'AdminLTE-2.0.6'; directoryPath = '/home/rstudio-user/R/x86_64-pc-linux-gnu-library/3.6/shinydashboard/AdminLTE'

all my libraries installed & loaded as the normal way

Do you want to share your project, or do you have a reproducible example you could share?
