Join is not a function (Missing exchanges and other default data in UI)

I'm submitting a ... [x] bug report [ ] question about the decisions made in the repository

Action taken (what you did) I tried to run UI and configure API key

Expected result (what you hoped would happen) Drop down menus would appear for exchanges

Actual result (unexpected outcome) No options for select box 'Exchanges'

Other information (e.g. detailed explanation, stacktraces, related issues, suggestions how to fix, links for us to have context, eg. stackoverflow, etc) MacOS High Sierra 10.13.6 node v11.5.0
