Just making sure I'm not missing something

If I pass something like ["a", "b", undefined] to a convex function, it doesn't get called but I also don't see any errors anywhere..

I know that undefined is scrubbed if passed as a single argument value to a function (more info from the Convex side in this thread), but I wouldn’t expect it to scrub an entire function call if a single array value is undefined.

@David Alonso How are you passing this? You should get an error like

However if you have a layer of indirection where you serialize the object yourself, it could be null:

Is there any way possible to get a line number on where the error is, my system is so complex now i cant find these, it takes at least a hour of placing console logs. One time it was a query was getting a object when i was looking for a insert. Or is there some general way to protect all convex functions from this. 😅 Im wondering if one of my functions is serializing a field starting with a underscore.. ive been indecisive about this object design and its screwed me over ugg this one caught me again.. i now remember.. the mutation attempts to serialize my payload on the final return and if a sub sub object doesnt searlize right its mostly invisible to me. I don't use a return validator for performance reasons. I think what is making this so hard is that both the console.log below in the function never output anything: so as far as im concerned the code is breaking before, but its only fixed if i fix the returned data or return void.

    console.log('END EVENT') 
    const eventData = Event.get() or new Event(oldEventData).get()
    console.log('eventData', eventData)
    return eventData

    console.log('END EVENT') 
    const eventData = Event.get() or new Event(oldEventData).get()
    console.log('eventData', eventData)
    return eventData

In your code snippet you have the literal word or instead of the "or" operator ||. Not sure if that could be contributing to any of the issues you're experiencing.

Yeah, its not that. I was just showing i had 2 ways of creating. I'd like to repo somehow, this has been the only time I've seen a error that prevents the console logs from outputting
