URL Shortener project for Microservices: Tests fail, but manual provision succeeds

JavaScript
#1

Tell us what’s happening:
When I click ‘I’ve completed this challenge’ I see that there’s a failure for the test:
When you visit /api/shorturl/<short_url>, you will be redirected to the original URL.

However, I’m logging the shortenedUrlsStorage variable, and when I past into the /api/shorturl/<short_url> using that, it correctly redirects me. This is regardless of whether or not the key appears to be a string in the output. This also is confusing since some of the keys don’t appear to be strings but still redirect when pasted into /api/shorturl/<short_url>

When I use curl to pass the url, I get a working redirect shorturl back:

:~> curl -d "url=www.google.com" -X POST https://boilerplate-project-urlshortener.seandoe.repl.co/api/shorturl
{"original_url":"www.google.com","short_url":"https://boilerplate-project-urlshortener.seandoe.repl.co/api/shorturl/bc7ab377c022c12a"}

The resulting shortenedUrlsStorage object after running the previous curl of the URL matching google is:

{
  '8d23e433cc3d215b': 'https://boilerplate-project-urlshortener.seandoe.repl.co/?v=1642180460583',
  cca0d1c3f9fa222b: 'https://boilerplate-project-urlshortener.seandoe.repl.co/?v=1642180460912',
  bc7ab377c022c12a: 'www.google.com'
}

Testing against one of those shortUrls, I’m seeing a successful redirect as well:

:~> curl -LI https://boilerplate-project-urlshortener.seandoe.repl.co/api/shorturl/cca0d1c3f9fa222b

This is the problem in the POST route:

  const successResponse = await promiseResJson(res.json({ original_url: providedUrl, short_url: `https://boilerplate-project-urlshortener.seandoe.repl.co/api/shorturl/${randomUrl}`}));

The response has to look like this (example from the test page):

{ original_url : 'https://freeCodeCamp.org', short_url : 1}

You don’t need to return a valid URL as the short_url; the client is expected to use the returned value to construct a new URL using your API.

Run the tests and look in the browser console and you’ll see the errors.

Once again, you’ve helped me get unstuck.
Thank you so much for taking the time.
