How to handle duplicates in Embedded Tweet


We are using the Embedded Tweets and it’s working well for users who have not done the ReTweet. The problem is that there are users who retweeted directly in Twitter. So when users are presented the Embedded Tweet in our application the “retweet button” does not seem to work as it’s not doing anything, no error message, no nothing. I was expecting our code in the retweet callback will kick in with an error - uur retweet callback works only for a successful retweet. What are we missing?
