[BUG] unable to catch exception from getVariable

[royyeh22]

Steps To Reproduce

Steps To Reproduce

1. have the following script:
   try{
       showToast(getVariable('not_in_global')); // not_in_global doesn't exist
       showToast(JSON.parse('{')); // '{' is not a valid json
   }
   catch (e)
   {
       showDialog(e.message, "ex");
   }

Expected behavior

exception from getVariable can be catched

Actual behavior

It pops up an 'Error' dialog and then aborts, when running into getVariable.
It's not like JSON.parse which indeed shows the customized 'ex'

This is intended behavior. getVariable requires that the variable exists. If the variable does not exist, the shortcut execution is aborted, as this suggests a configuration error and needs to be fixed by the user.
