Unable to update row in table 'X'. → Unable to save image → Request had insufficient authentic

[V-A]

I'm getting the below error when I attempt to upload an image using my app:

"Unable to update row in table 'X'. → Unable to save image → Request had insufficient authentication scopes."

I've tried the app with different app owner- and non-owner privileges along with different devices and have the same experience, i.e. error without the image uploading.

Troubleshooting suggestions are appreciated.
