I face this error after deploy my app. Whenever i tried to solve the issue and redeploy the app, I face the error , but the only thing that each time change is the name of the function. for example here is "leafletOutput". in my previous attempt to solve the error, the name of function changed. i do not know that "could not find function " pertain to what issue.
The application failed to start (exited with code 1).
Error in value[[3L]](cond) : could not find function "leafletOutput" Calls: local ... tryCatch -> tryCatchList -> tryCatchOne -> <Anonymous> Execution halted
