TypeError: e.map is not a function

[LisaP117]

Bug Unable to get into entries on the CMS to update my pages due to error page being presented. "TypeError: e.map is not a function"

To reproduce I log in to Netlify CMS, navigate to pages, click on index and then am presented with the attached screenshot.

What I expect I would expect to log in, navigate to pages, select the index page and be presented with editable boxes.
