Invalid response format when using sendRequest on android

[idanlo]

i'm trying to reach this endpoint https://developer.spotify.com/documentation/web-api/reference/follow/check-user-following-playlist/, my code looks like this:

Spotify.getMe().then(res => {
    Spotify.sendRequest(`v1/playlists/${playlistId}/followers/contains`, "GET", { ids: res.id }, false)
        .then(isFollowing => {
            console.log(isFollowing)
    })
})

but I get the following error:

Possible Unhandled Promise Rejection:
Error: Invalid response format

i tried to do this request with the same data on their web console and it worked.

I only have an android device so I don't know what happens on IOS.

@idanlo I think I've run into a similar issue but I would need to validate before really diving into it. If you through a catch after you then, do you mind outputting what it shows?
So it would look like this:

Spotify.getMe().then(res => {
    Spotify.sendRequest(`v1/playlists/${playlistId}/followers/contains`, "GET", { ids: res.id }, false)
        .then(isFollowing => {
            console.log(isFollowing)
         }).catch(err => {
            console.log(err)
         })
})

What I'm seeing in my console for both playlists/${playlistID}/followers/contains GET request and the playlists/${playlistID}/followers DELETE request is the error message of Error: Service not found

I'm on iOS but I would imagine the same thing...so I tried going into RNSpotify.m and debugging and I got as far as inspecting the request on line 961 of [[SPTRequest sharedHandler] performRequest:request callback:^(NSError* error, NSURLResponse* response, NSData* data)

The response from this request comes back as:
{"error": {"status": 404,"message": "Service not found"}} but again, as you say, it works in the console and postman. The SPTRequest is coming from the Spotify framework...so I wonder if it's a version problem? I don't quite know why it would fail as I would assume it is just an API request,but maybe?

If you dont mind sharing if that's the same error you are receiving I think we can debug this more. Right now it seems like there may be something up with the playlist/.../followers endpoints on the Spotify framework side.

Update - if this is still causing you problems and it is a problem with the SDK version, you can always get the access token from getSession and then use your own api request (axios, fetch, etc). to send a request to the Spotify API. I just did that and it works for me 🤷‍♂️
