Illustrator error occurred 1346458189('MRAP') while accessing font color after closing a doc

Question

I have a jsx script that retrieves the font color of every TextFrame object in the active document and does a couple of math ratio checks.

The script runs fine when i run it on an active doc, i have tried running it 5-10 times without any issues repeatedly. It also works when I open a new doc with the old doc still open in a tab, and again it works repeatedly.

However the minute I close an active document, and try to rerun the script on another doc (new or open in a tab), I am running into this error "Illustrator error occurred 1346458189('MRAP')" .
the error is always thrown at this specific line

pageItem.textRange.characterAttributes.fillColor

i have tried the suggested solutions of $.gc() and reducing variables used in loops to no avail. I think this is more a Illustrator bug as it happens in a very specific scenario of closing an active document and is not specific to any doc.

The rest of the code runs fine always.

Any help/suggestions would be appreciated!

All the other parts of the code run fine

I have run into these MRAP issues and its typically when a document hasnt been saved or there isnt an object I think there is or even an item with effects which show up as plug-in items. I would start by checking for textframes with fills and then loop through those first. If your looking for text frames and trying to get their fill colors when something isnt filled or have an empty text frame without characters youll have these errors.
