Errors on homepage when using EU instance #61
Description
I had all kinds of errors on the homepage stating that my api key was incorrect when I used CONTENTSTACK_API_HOST=app.contentstack.com, but when I used CONTENTSTACK_API_HOST=eu-app.contentstack.com (I'm from the EU) the urls that tried to retrieve the info didn't work at all. I think it's because the eu-app uses a prefix /api before the /v3 that the us maybe doesn't use?
Anyway, I circumvented this issue by adding url: 'https://eu-app.contentstack.com/api' to contenstack-sdk/index.js:36. This prefixes the urls and now I see some things on the page, although there are still errors.
Please try to create a eu instance and see if the code actually works. I followed the instructions of the developer training.
