I'm trying to get searchkick to reindex on the heroku application. It currently reindexs fine on the localhost.

The command i run on localhost is this

```
rake searchkick:reindex CLASS=Newevent

```

I've been following the github tutorial and got to this

```
heroku run rake searchkick:reindex CLASS=Newevent

```

Which currently returns this, 

```
 heroku run rake searchkick:reindex CLASS=Newevent
Running rake searchkick:reindex CLASS=Newevent on //APPNAMEREMOVED//... up, run.7334
rake aborted!
