ExtendScript Change Graphics Source Text not working

[rubberducking]

I am using Adobe Premiere Pro 2023 and I am trying to edit a Graphics Layer's Source Text using ExtendScript. Everything I try to do it, it sets the Graphics Layer to a blank and removes all the text instead of setting the value

Here is what I am doing:

app.project.activeSequence.videoTracks[2].clips[0].components[3].properties[0].getValue('Hello', 1); 

I would expect the item to be updated to be updated to "Hello"

Note, this Graphics item was generated using Captions and then using the "Upgrade to Caption to Graphics" function

Chaining that many function calls makes it impossible to detect which failed. Also, without the actual project you're using, it's impossible to tell whether that call should work. 

PPro's .mogrt-related API calls are designed to work specifically with .mogrts generated in After Effects.

In the PProPanel example code around inserting and manipulating AE-generated .mogrts, it's necessary to call trackItem.getMGTComponent(), to access the variable params exposed by that .mogrt. Does that call succeed, for the trackItem you're attempting to modify, above?
