MongoParseError on Heroku Deployment

Hi Meteor Community,

I was trying to deploy my app onto Heroku and it successfully built, but once I went to the actual Heroku page, I got an error message telling me to check the Heroku command logs. It said there was a ‘MongoParseError: Invalid Connection String’. Do any of you know what may have caused this or what I can do to solve this?

Thank you for your generous help,


Did you set up your environments vars correctly?


Thank you for the response. This was the problem in the end.

Thanks again,
