This could be beneficial for using some shortcodes such as Instagram, for example.
instagram shortcode: Missing config value for services.instagram.accessToken. This can be set in config.toml, but it is recommended to configure this via the HUGO_SERVICES_INSTAGRAM_ACCESSTOKEN OS environment variable. If you are using a Client Access Token, remember that you must combine it with your App ID using a pipe symbol (<APPID>|<CLIENTTOKEN>) otherwise the request will fail.
If you feel that this should not be logged as an ERROR, you can ignore it by adding this to your site config:
ignoreErrors = ["error-missing-instagram-accesstoken"]
