java.lang.IllegalStateException: YouTubeServiceEntity not initialized with YouTubeThumbnailView

I am using youtube api in my android app to load thumbnails for videos in my RecyclerView. Following is my implementation in side my adapter:

private final Map<YouTubeThumbnailView, YouTubeThumbnailLoader> thumbnailViewToLoaderMap;

This holds the loaders for the YouTubeThumbnailView for each adapter element. This is the code we use for initialisation of the YouTubeThumbnailLoader(s):

    YouTubeThumbnailLoader loader = thumbnailViewToLoaderMap.get(holder.thumbnail);
                final String videoId = Utils.getYoutubeIdFromUrl(m.getYoutubeUrl());
                holder.thumbnail.setTag(videoId);
                if(loader != null) {
                     loader.setVideo(videoId);
                    }
                }

When initialising the elements of the ViewHolder, I initialise the thumbnail loaders as follows:

private void setupYoutubeThumbnail() {
            thumbnail.initialize(RiyazApplication.applicationInstance
                            .getString(R.string.youtube_api_developer_key),
                    thumbnailListener);
            thumbnail.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    if(v.getTag() != null && itemClickListener != null) {
                        itemClickListener.onClickVideo(mList.get(getAdapterPosition()));
                    }
                }
            });

and the code for releasing the thumbnail loaders is as follows:

public void releaseThumbnailLoaders() {
        final Set<YouTubeThumbnailView> keysSet = thumbnailViewToLoaderMap.keySet();
        for(YouTubeThumbnailView view: keysSet) {
            final YouTubeThumbnailLoader loader = thumbnailViewToLoaderMap.get(view);
            if(loader != null) {
                loader.release();
            }
        }
        thumbnailViewToLoaderMap.clear();
    }

In my crashalytics, I am getting the following exception:
