I created an environment variable in config and it works for me but when I run it I get this, does anyone have any idea why it happens?
You have configured application :distributor_public_key in your configuration file,
but the application is not available.
This usually means one of:
1. You have not added the application as a dependency in a mix.exs file.
2. You are configuring an application that does not really exist.
Please ensure :distributor_public_key exists or remove the configuration.
I mean sometime You use the name of the plugin You want to configure… for example waffle. That is why it is not alway the name of the main application.
