Firebase API call fails

Hey, I keep hitting a problem with the call to Firebase. I've tried 5 different ways, but I keep getting this error when I hit: "Go To Notes":

I've created a new firebase app 3 times, tried using the sample url, but nothing seems to work. Can you help?

Thanks, Casey

I've been banging my head against this for almost 4 days now... it seems like the Firebase API went through a lot of changes and this code isn't valid anymore.

What's funny is that a simple GET request to the REST API works, but never within Xcode. I've experimented with sending headers, setting body to null for a GET request... and still every call fails. No clue :(

So, I may have figured it out. -Go into the app/utils/api.js file -Change all the declarations of const url =... to let url =...

Not sure why it works, but it does apparently work. I guess we are setting url to be the github-fetching url, so redefining it doesn't actually work. Admittedly, this seems like a subpar explanation. If I could get a better explanation, I'd be happy about it

Anyway, give that a shot & let us know if it works for you too

@caseyrider Tried making all my var's let, as I didnt have them as const and still no luck. :(

Also tried this code base and it worked fine, only fail's within my code base. Doesn't make sense to me.
