STEPS
---------
The issue can be reproduced with the following steps: 

1. Access a portal that contains the Document Explorer task flow and click ‘Upload’ to upload a document
2. Click on 'Select files'
3. Select a file to upload
4. Click 'Upload'
5. The page displays a small 'HTTP Error.' next to the file:

6. When clicking the ‘Upload’ button, the page now shows “Unable to upload the document”:

Due to this issue, users cannot upload documents.
