How to get Sentry 7.5.2 disabled in :dev mode?

Hello,

Fairly new to Elixir here so please be gentle Our codebase is using Sentry 7.5.2. (I know that is old but I’d prefer to worry about updating it to something newer at a later time.) I am running in :dev mode but it seems like Sentry is running along with me and I think intercepting things that I’d like to see.

I am in :dev mode:

iex(113)> Mix.env()
:dev

Here are the Sentry-related environment vars as seen from inside the app:

iex(107)> System.get_env("SENTRY_DSN")
""
iex(110)> System.get_env("SENTRY_ENVIRONMENT_NAME")
""
iex(111)> System.get_env("SENTRY_INCLUDED_ENVIRONMENTS")
""
iex(115)> System.get_env("SENTRY_RELEASE")
nil

But then I see this sort of log message indicating that Sentry is trying to do something:

{
  "app": "sentry",
  "gl": "#PID<0.909.0>",
  "level": "warn",
  "message": "Failed to send Sentry event.Cannot send Sentry event because of invalid DSN",
  "metadata": {
    "domain": [
      "elixir"
    ],
    "request_id": "F5wrctA25-Dau_cAADkB",
    "time": 1701282531378937
  },
  "module": "Elixir.Sentry.Client",
  "pid": "#PID<0.30278.0>",
  "timestamp": "2023-11-29T18:28:51.000378"
}

Here are ref’s to sentry in config files:

% grep -ir sentry config
config/config.exs:  backends: [:console, Sentry.LoggerBackend],
config/config.exs:config :logger, Sentry.LoggerBackend, include_logger_metadata: true
config/config.exs:config :sentry, included_environments: []
config/releases.exs:config :sentry,
config/releases.exs:  dsn: System.get_env("SENTRY_DSN"),
config/releases.exs:  environment_name: System.get_env("SENTRY_ENVIRONMENT_NAME"),
config/releases.exs:  included_environments: System.get_env("SENTRY_ENVIRONMENT_NAME"),
config/releases.exs:  release: System.get_env("SENTRY_RELEASE")

Short of updating Sentry, how can I get Sentry to not run while in :dev mode?

Thanks humbly in advance… Chris
