getUserPlaylists issue with undefined userId

[neilime]

I need to retrieve the first 50 playlists of current user.

Typescript definition of function getUserPlaylists : getUserPlaylists(userId?: string, options?: Object,... suggest to do : getUserPlaylists(undefined, {limit: 50});

I does not work...

Actually the function getUserPlaylists does not work as expected according to the doc and typescript typing.

If the userId is not a string (undefined or anything else), the first argument become the options.

But in typescript you cannot pass an object as the first argument because it must be a string or undefined.

I had the same issue! Since I don't use Typescript I was able to just use the first parameter as options, but my IDE is not happy of course. And for me it was very confusing figuring out why it didn't work initially.

I faced the same issue. A workaround is adding // @ts-ignore before the function call.

I had the same issue, and I dug a bit in the source. Here's what I found if it could help:

• When calling getUserPlaylists(undefined, { limit: 20 }) with userId as undefined, the options get replace with userId and options are forwarded to callback https://github.com/JMPerez/spotify-web-api-js/blob/b0c0143c961c5ebed699a450471ad47820e64ed2/src/spotify-web-api.js#L676-L690
• Then _checkParamsAndPerformRequest is called with _checkParamsAndPerformRequest(requestData, undefined, { limit: 20 }), and it turns out the options and the callback are removed from the request https://github.com/JMPerez/spotify-web-api-js/blob/b0c0143c961c5ebed699a450471ad47820e64ed2/src/spotify-web-api.js#L143-L162

I got around this issue by requesting the userId and calling getUserPlaylists(userId, { limit: 20 }) instead.
