solution 👍
only needs to add single line ie . if (!image || !image.media_details || !image.media_details.sizes) return '';
in getImageThumbnail function
var getImageThumbnail = function getImageThumbnail(image) {
if (!image || !image.media_details || !image.media_details.sizes) return '';
if (image.media_details.sizes.thumbnail) {
return image.media_details.sizes.thumbnail.source_url;
}
return '';
};
