Javascript error when using reviews widget iframe

[Pranit]

Hi,
We observe js errors when using reviews_widget_iframe API. It might be because of the cross domain policy.

Example URL:
https://ebookstore.sony.com/ebook/e-l...

API URL:
https://www.goodreads.com/api/reviews...

Do you see any possible solution to get rid of these two errors? If not, any alternatives that you can suggest?

Thanks,
Pranit
