Error creating original document diff: TypeError: Cannot read properties of undefined (reading 'split')

[saoshreyas]

The createPatch() function from the diff library is receiving undefined where it expects a string. One of the values you're passing to it (likely the "original document" content) is undefined — meaning you're probably trying to diff a document before its content is loaded, or an annotation's document field is missing. The plan is to add a check before the function.

Retagging is probably broken right now because of the streaming issue we just fixed for extensions, but I'll need to check further. I should create a separate issue for that.

This is basically line 59 of AnnotationTracker.ts, either global or originalDocument is probably undefined.

I notice that this error only seems to occur when annotations for the quicksort.js file are opened, and not when any other file is opened, including newly-created files. Maybe this is an issue with the annotation definitions in that file being out of date or orphans existing in there?

This can be tested by nuking the annotation data and building the same annotations from scratch and checking if the error still occurs. @saoshreyas if you get copilot access you can test this, lmk if you need help with it
