Empty Object Response from API call (via AJAX)

[jrkang8]

Hi all

I’m using AJAX call to hit Kraken API. This was working yesterday night.

$.ajax({
type: ‘GET’,
url: ‘https://api.twitch.tv/kraken/search/streams?q=starcraft’,
headers: {‘Client-ID’: ‘xxx’},
success: function(data) {
console.log(data);
}});

It successfully populated _total, stream array, etc.

However, the API went down today, and after it came back up, this call is now returning just:

Object {_total: 0, _links: Object, streams: Array[0]}

What is going on?

Probably a caching issue that stemmed from when Twitch had a brain aneurysm a short while ago. Should hopefully be back up soon

For example, “https://api.twitch.tv/kraken/search/channels?q=starcraft” is working right now, so probably just a bit until all end points are back up.

If it’s still not returning anything within an hour or two then probably something is up.

Thank you

One thing I wanted to bring up: I tried changing “{‘Client-ID’: ‘xxx’}” to {‘Client-ID’: ‘’} and it still returned the empty JSON object. Shouldn’t it give me a bad request if the client ID is empty/wrong?

I’m not familiar with AJAX so i’m not sure how it handles a bad request, but when I view it on my end without a valid Client ID then I see the expected error messaging.

{“error”:“Bad Request”,“status”:400,“message”:“No client id specified”}

You may need to include proper error handling to see this messaging - a quick google provided the below example:

function handleAjaxError(jqXHR, textStatus, errorThrown) {
if (jqXHR.status == 500) {
// Server side error
} else if (jqXHR.status == 404) {
// Not found
} else if (jqXHR.status == 400) {
//Bad request
}
}

$.ajax({
CODE HERE
success: function() { … },
error: handleAjaxError
});

I’m able to see the error message in console. If I omit the “headers” line completely from my request, I see {“error”:“Bad Request”,“status”:400,“message”:“No client id specified”}.

But if I keep the headers line but remove my client id, or if I replace my id with just a bogus id, it still returns an empty object as a response (and no errors). Do you think this is due to the caching you mentioned above?

[Larklen]

Hmm I would still expect it to give the 400 error in a scenario where a invalid Client ID is provided or none at all, so I think it’s weird that you are seeing a different outcome (as in, no errors populated.) Though, I could be misinterpreting (or misunderstanding) something with AJAX due to my limited knowledge on it

It may be a remnant of the server issues - as I still see zero results returned for this one (even with other games).

[jrkang8]

Still having this issue…Do you still see zero results for this one? Thank you so much for working with me.

[Larklen]

Just checked it now and I got 76 objects returned so it looks like it’s back up and running!

[jrkang8]

Yep same! Thank you
