Photoshop supress stop on actions

I've got an action that takes a while. Like go and make a cup of tea kind of long.  It now starts popping up continue messages for the user to prompt on an error - which is image subjective:

I thought I could switch prompts off with code using:

// Switch off any dialog boxes
displayDialogs = DialogModes.NO;

Toggle dialog on/off on teh action doen't make adifference as this is error (selection) based

Is there a on error auto continue way forward?
