Suppress error dialog in automator

Question

hi,
sometimes my automator app outputs an error dialog "watchmedo encountered an error".
this blocks the app to be restarted automatically (I schedule my apps on a repeated basis), as the app is still open.
how can I suppress error dialogs like this? or can I quit the app once an error is encountered?
those error dialogs (which only go away by clicking OK) kill the possibility to restart the app automatically ...
thanks.

Hmmm - it is supposed to throw an error when getting the ID.  Another way would be to assign the ID to a variable, although you will need to enclose your application terms in a using terms from statement so that the compiler will know what application dictionary to use:
set theID to "com.apple.missingSafari" -- add/remove "missing" to test
try
    using terms from application "Safari"
        tell application id theID -- error if the ID doesn't exist
            get URL of tab 1 of window 1 -- or whatever
        end tell
    end using terms from
on error errmess
    beep
    log errmess
end try
