Error loading my application in

Hi! I load my app in but when I run it it returns an error:
An error has occurred
The application failed to start (exited with code 1).

Error in value [[3L]] (cond):
   "dashboardPage" function could not be found
Calls: local ... tryCatch -> tryCatchList -> tryCatchOne -> <Anonymous>
Execution interrupted.

Locally I have no problem executing it and I have all the packages installed.
Can someone guide me?
