Dyno Sleep: If you are on a free tier and you don’t access the application for a while Heroku will put your dynos to sleep. You can fix this by upgrading the dynos to paid tier.
Ephemeral Storage: Heroku has an “ephemeral” hard disk. The files uploaded to Chatwoot would not persist after the application is restarted. By default, Chatwoot uses local disk as the upload destination. To overcome this problem, you will have to configure a cloud storage.
Build Version: If the build version is shown as unknown on the settings page, enable the runtime dyno metadata feature. To enable, use:
Copy
heroku labs:enable runtime-dyno-metadata -a <app-name>
