com.dropbox.core.ServerException when getting file list from dropbox

Hi, I'm getting com.dropbox.core.ServerException when requesting file list from account. Few hours ago it worked fine, but now it's crashing.

y = mClientV2.files().listFolderBuilder(mPoint).withRecursive(true).start();

while (true){
    for (Metadata metadata: y.getEntries()){
        // some job
    }

    if (!y.getHasMore()){
        break;
    }

    y = mClientV2.files().listFolderContinue(y.getCursor());
}
