Can't connect to Nightscout if Nightscout URL has trailing slash

[seanknox]

Describe the bug
User gets Nighscoutuploadkit.Uploaderror error 0 when setting up Nightscout if the Nightscout URL has a trailing slash (e.g. https://myappname.herokuapp.com/ vs https://myappname.herokuapp.com)

Attach an Issue Report
Tap the Loop settings icon on the bottom of the screen, then tap Issue Report and attach it to this ticket.

To Reproduce
Steps to reproduce the behavior:

1. Go to settings
2. Tap to set Nightscout
3. Enter NS URL with a trailing slash

Expected behavior
Loop accepts Nightscout URL or sanitizes it (removes the trailing slash).

Actual behavior
Loop returns Nighscoutuploadkit.Uploaderror error 0. I've tried multiple different (new) Nightscout sites and confirmed the API Key is correct.

This seems like Loop can't authenticate to Nightscout. I've confirmed the API is correct by logging into the Nightscout web UI.

I had this issue and I had recently changed my API key. I found that I had to restart my NS instance for the new API key to take. I see though you’re using Heroku, whereas I am running NS on my own Linux VPS.

Make sure your URL doesn’t have a trailing slash in Loop settings too

It was the trailing slash in the URL! Great find.

Well, to be fair to the docs...it is in there. ;) https://loopkit.github.io/loopdocs/operation/loop-settings/services/#nightscout

[seanknox]

True, though a user really shouldn't have to ensure that text input like this is sanitized; the app should do that. I'm going to see if I can make that happen.

I wish you could edit what you have entered. It took me three tries of typing the URL in several variations and the lengthy API Secret. As you have to Delete and start over.
