[voger]

I followed the instalation instructions and I got this error

$ mix phoenix.server

The solution was to copy this block from config/prod.exs to config/dev.exs and change the environment_name to :dev

config :sentry,
  use_error_logger: true,
  environment_name: :prod,
  dsn: System.get_env("SENTRY_DSN"),
  tags: %{
    env: "production"
  }

Yes, your solution is correct. I have used the following code in my config/dev.secrets.exs file.

config :sentry,
  use_error_logger: false,
  environment_name: :dev,
  dsn: System.get_env("SENTRY_DSN"),
  included_environments: ~w(prod)a,
  tags: %{
    env: "development"
  }

I will add this to to README.
