Unsupported Button Deploy

Your Heroku Button Deployment Could Not Be Completed

We were unable to automatically deploy this application using the Heroku Button. This is likely because older Heroku Buttons relied on information that is no longer consistently available due to browser security updates that previously allowed us to infer the source repository.

• Good News: The maintainer(s) of this button can restore functionality by updating its implementation to use the latest Heroku Button format.
• What to do: If you know who maintains this button, please let them know that an update is needed. A good place to start would be opening an Issue in the repository or referencing its README for contact information.
