How to Replicate

1. Create a word document with many images attached to it
2. Upload it to any Cloud instance, via ... >> Import Word Document (don't need to split headings)

Investigation Done

• Import works fine if the images in the document are removed
• No OOME as far as we can see
• The following errors are thrown:

Workaround

Only workaround now is to remove the images in the Word document and attach them manually to the page post-import
