Question

I'm uploading videos to Twitter using the Rest API through Retrofit but, sometimes, I get the Internal Server Error (500) on retrofit logs: {"errors":[{"code":215,"message":"Bad Authentication data."}]}

The authentication process is done using Fabric:

 TwitterAuthConfig authConfig = new TwitterAuthConfig(CONSUMER_KEY, CONSUMER_SECRET);
 Fabric.with(this, new TwitterCore(authConfig), new TweetUi());
 twitterLoginButton.setCallback(new Callback<TwitterSession>() {

        @Override
        public void success(final Result<TwitterSession> result) {
            // Calls method to let user chose a media to upload
        }

        @Override
        public void failure(final TwitterException exception) {
            // Do something on failure
        }
    });

After select the video and try to post, I do the following verification:

AccountService accountService = TwitterCore.getInstance().getApiClient().getAccountService();
accountService.verifyCredentials(false, false, new Callback<User>() {

            @Override
            public void success(final Result<User> result) {
               // Calls retrofit to init upload video process 
            }

            @Override
            public void failure(final TwitterException exception) {
                // Do something on failure
            }
        });

And the retrofit call follows this:

@FormUrlEncoded()
@POST("/1.1/media/upload.json")
void uploadVideoInit(@Field("command") String command,
                     @Field("total_bytes") String totalBytes,
                     @Field("media_type") String mediaType,
                     Callback<T> callback);

@Multipart
@POST("/1.1/media/upload.json")
void uploadVideoAppend(@Part("command") String command,
                       @Part("media_id") String mediaId,
                       @Part("media") TypedFile media, // The raw binary file content being uploaded. Cannot be used with media_data.
                       // Required after an INIT, an index number starting at zero indicating the order of the uploaded chunks.
                       // The chunk of the upload for a single media, from 0-999, inclusive.
                       // The first segment_index is 0, the second segment uploaded is 1, etc.
                       @Part("segment_index") int segmentIndex,
                       Callback<T> callback);

@POST("/1.1/media/upload.json")
@FormUrlEncoded()
void uploadVideoFinalize(@Field("command") String command,
                         @Field("media_id") String mediaId,
                         Callback<T> callback);

The tweet part is like this:

@FormUrlEncoded
@POST("/1.1/statuses/update.json")
void update(@Field("status") String status,
            @Field("media_ids") String mediaIds,
            Callback<T> callback);

It works, but, it's not difficult I receive the mentioned above error, usually during de APPEND part of the process. I try to upload short videos and also those with the maximum duration allowed (about 30s), but it's the same scenario.

I'd like to know if I need to add some parameter to each request, like the user's token or if the user credentials expire soon than expected. Up until now I haven't found out what's missing or wrong.

Thanks in advance.
