Attempting to set up deploy notifications to Airbrake on Heroku deploy with rake airbrake:heroku:add_deploy_notification
when you have multiple Heroku apps (i.e. git remotes) will yield:
! Multiple apps in folder and no app specified.
! Specify app with --app APP.
It appears Airbrake are aware of this but no real solution is offered.
Is there a work around?
A fix has now been pushed for this.
You can set the environment variable HEROKU_APP
to the name of the app.
