I'm currently developing an Add-In for powerpoint. The basic features are:
- Select the current slide
- Select all the shapes and its textFrame
- Send all the found text to my backend to check for grammar/spelling errors
- Send response back and underline the textRange by the offset and length from my backend.
Everything seems to go well with a simple slide of just text boxes or shapes with texts.
The issue seems to come when a slide has text boxes inside a box that controls the text boxes size (see below image).
The error isn't so clear:
RichApi.Error: InvalidArgument
This part gets highlighted when I check the log/source
I took the two text boxes outside of that wrapper (the extra square around the two text boxes), and it went just fine. Why?
