Heroku Restart Error


#1

Hi,
I got this error on restarting heroku server
2016-05-07T12:12:43.298117+00:00 app[web.1]: 12:12:43.297Z WARN Reaction: Error while importing to Shops: E11000 duplicate key error index: heroku_jm69t5vc.Shops.$id dup key: { : “J8Bhq3uTtdgwZx3rz” }

Somehow reaction generated a new shop on restart.
