Today I ran into another case where this happened, not b/c of an invalid URL but simply due to a bad response from the iTunes API:
<html><head><title>Error</title></head><body>Your request produced an error. <BR>[newNullResponse]</body></html>
Trying the request again worked fine. It appears that once in a great while the iTunes API doesn't work, which is to be expected from any real-world API I suppose. It could be a rate limiting feature (happened when I was making a bunch of requests to autocomplete some search results), but I'm not sure.
Regardless, I submitted a PR that handles invalid JSON from the iTunes API. By decoding the response with phar
instead of manually, the Promise is rejected instead of a fatal error being thrown that aborts the Node process. In my case, it's the difference between my Fastify
server's Node process being shut down and it being able to continue to handle requests.

This happens if the iTunes URL gets screwed up, for instance if you pass an ItunesEntityPodcast
object instead of a podcast
string as the entity (as I mistakenly did)
import {
searchItunes,
ItunesSearchOptions,
ItunesEntityPodcast,
} from 'node-itunes-search';
async function search() {
const results = await searchItunes(
new ItunesSearchOptions({
term: 'this american life',
entity: ItunesEntityPodcast, // Should be a "podcast" string, not an object
limit: 10,
})
);
}
In the above case, the requested URL is invalid:
https://itunes.apple.com/search?term=revisionist&entity=[object Object]&limit=1
If you paste this URL into your browser you'll see a JSON error message in response--I think b/c the browser is url-encoding the square brackets. If you try it with curl
it'll give you an error message, e.g.
$ curl "https://itunes.apple.com/search?term=revisionist&entity=[object Object]&limit=1"
curl: (3) bad range in URL position 58:
https://itunes.apple.com/search?term=revisionist&entity=[object Object]&limit=1
^
Likewise, phin
balks at this and will populate res
in search.js
with a buffer instead of a string. I tried converting the buffer to a string, but when I do this I get back a bunch of strange characters, not the JSON I'd expect.
I think the best solution would be ensuring the URL is valid before making the request, such as by using the URL()
constructor.

Just for reference, here's the exact error I ran into:
undefined:1
<html><head><title>Error</title></head><body>Your request produced an error. <BR>[newNullResponse]</body></html>
^
SyntaxError: Unexpected token < in JSON at position 0

Just published the new release 😄! I really appreciate the help @micahjon!

I can't seem to reproduce this, do you recall the structure of the request?

Hey @jacob-shuman, thanks for merging #18 . Looks like we just need a new npm release and then we can close this issue.
