But that's the error you're getting, isn't it? Try doing this:

fetch(api)
   .then(response => {
      console.log('Response:', response)
      return response.json();
})

And let us know what you get in the console after Response:

Logging the response will help, but a quicker approach to debugging this would be to run it in the browser with dev tools open on the network tab and confirm that:

  • the request you're making is properly formed: e.g. string parameters are included as expected
  • the response is what you expect: i.e. json

You can see the contents by selecting the response in the list and it'll then show tabs where you can expand details

It's a different approach, I wouldn't say it's "quicker".

There's nothing wrong with console.log, but it soon becomes tedious adding and removing it from your code. That definitely takes longer than hitting
F12 + a couple of mouse clicks to get to the Network tab; which doesn't even require you to open your editor.

Right, but the person you replied to said about adding one console.log

I wasn't being critical of the previous response. I just pointed out that in this context there's another approach that doesn't require console.log; that is certainly quicker; and that also illustrates a really useful debugging tool.
You however are adding nothing to the conversation...

I didn't say you were, but you're wrong when you say it's quicker. Depending on skill level, it could take a lot longer.

Even with a high skill level, sometimes a quick console.log is best.

I think you need to calm yourself down.

ROFL. You're being utterly pedantic. That's like saying a hand drill is quicker for someone who doesn't know how to use an electric drill. In the context described - i.e. debugging network requests - the network tab will always be the quickest way to see the result of a failed response.

As I said: I added this as a potentially useful avenue of learning (which may indeed be slower for those unfamiliar with the browser debugger; but will save them a lot of key-strokes in the long run). I don't see what you are adding to this conversation: are you saying we shouldn't suggest better solutions when they are available?

And it's going to take more than a couple of passive/aggressive comments to bring me out of my calm zone :D
