error when submitting a onenote assignment containing an image

[SYoung3000]

We've had a report from a customer who has observed a replicatable bug - this has occured on 4.2 and 4.5 with various releases of the onenote submission plugin, though we've only recently identified how to replicate issue on the latest release of onenote.

Broadly it appears that when we submit to an assignment and it contains text, all is fine. When the submission contains an image, we receive the following error.

Note that this only happens when trying to view the submission. When the student tries to edit their submission, it's fine.
