Cant load data in shape tags for powerpoint add-in

Question

[stripped whining]

My current issue is that I am trying to get a list of shapes, and check the tags for each shape and if I find a specific tag, I do something with it.

This worked at one time, and I am not sure what changed to make this no longer work.

What is happening now is that I am getting the following error message while trying to read tag.value: RichApi.Error: GeneralException.

I have tried multiple different ways to get this data (see below), so the error has been different places. Right now it is showing that the offending statement is var tag = tags.getItem("mc-accessToken");, but earlier it was at (!tag.isNullObject) and then await this.replaceExistingDiagram(tag.value); (on tag.value)

Can someone please direct me to a resource that can help!

My original code was as follows:

await PowerPoint.run(async (context) => {
      const presentation = context.presentation;
      const slides = presentation.slides.load("items");
      await context.sync();

      for(let slideIndex = 0; slideIndex < slides.items.length; slideIndex++) {
        const slide = slides.items[slideIndex];
        const shapes = slide.shapes.load("items");
        
        await context.sync();

        for (let shapeIndex = 0; shapeIndex < shapes.items.length; shapeIndex++) {
          const shape = shapes.items[shapeIndex];
          const tag = shape.tags.getItemOrNullObject(C.TokenSettingName);
          if (!tag.isNullObject) {
            shape.delete();
            await this.replaceExistingDiagram(tag.value);
          }
        }
      }
    });

I have made different changes to try and make sure that I am loading the properties I need My current iteration of code looks like this (only showing changes):

        const shapes = slide.shapes.load('items');
        await context.sync();

       for ... {
          const shape = shapes.items[shapeIndex];
          shape.tags.load("key, value");
          await context.sync();
          
          ...
        }

I have also tried:

• const shapes = slide.shapes.load('items, isNullObject');
• const tag = shape.tags.getItem(C.TokenSettingName);
• shape.load('tags');
• shape.load('tags');
• const tag = shape.tags.getItem(C.TokenSettingName); tag.load('value');
• shapes.load("tags/key, tags/value");

( I just found this: shapes.load("items/$none");, would I need to do something like shapes.load("items/tags");?)
