Image Upload as a Visitor

Hi,
I am testing the demo, and in a local install and at https://demo.appyapp.io/images/create
a visitor cannot upload an image. In the frontend, it's stuck "Finalizing..." and on the backend, the local logs show:
`[18:08:09.642] 8433 ERROR node_modules/rest-hapi/utilities/handler-helper.js:380:11 api/generate-routes/Visitor — ValidationError:visitor validation failed: ip: Path `ip` is required.

Reproduce the failure at https://demo.appyapp.io/images/create and inspect the frontend state when it remains "Finalizing...". Then trace the backend api/generate-routes/Visitor path using the reported Mongoose validation error for the required ip field. Done means a visitor can upload an image successfully in both local and demo environments without that validation error.
