Error while GeoTargetting a Twitter Post


We are trying to geo-target a Tweet using twitter API. While it works for most of the twitter accounts that we have, its failing for one of them.
Error that we are getting while tweeting it is:
exception:Twitter::Error::AlreadyRetweeted(Not authorized to use this endpoint.)

We are sending a different tweet every time, so its certainly not a duplicate of an existing tweet.
Twitter handle for this account is : @EdCho3

Please note only geo-targetted tweet for this account fails, normal tweets just go fine.

Can anyone explain what this error implies ?
