My application doesn't seem to know what to do with "en" as a locale. What am I missing?

I've looked at the documentation a few times, but I'm pretty sure I've done the correct setup. Did my best to search on Google for this specific message.

My working assumption is that you have a ex_cldr locale, :en, configured. That you are also using the plug Cldr.Plug.PutLocale to set both the ex_cldr and the gettext locales. Furthermore, that you do not have a gettext locale called "en" configured.

You could validate this by doing the following in iex:

# This example is my development configuration. Subsitute using
# your own `gettext` backend module and your own `ex_cldr` backend
# module.
iex> Gettext.known_locales(MyApp.Gettext)
["bg_BG", "en", "en_GB", "es", "it"]
iex> MyApp.Cldr.known_locale_names()
[:ar, :bg, :ca, :"ca-ES-valencia", :da, :de, :doi, :en, :"en-001", :"en-AU",
 :"en-GB", :es, :fr, :"fr-CA", :hr, :it, :ja, :nb, :nn, :no, :pl, :sr, :th, :to,
 :zh, :"zh-Hant-HK"]

Additional information

If that doesn't trigger an "ah hah" moment, then the following information will be most helpful to explore further:

1. Your ex_cldr backend module configuration (the use Cldr .....).
2. Your gettext locales (the output of Gettext.known_locales(MyApp.Gettext)).
3. The configuration of your Cldr.Plug.PutLocale plug (for now I'm assuming thats in use since thats where the log message comes from iirc).

If you have any suggestions on how I can improve the getting started documentation I'd be very open to that too if you're willing.

Hey Kip, so sorry for this being late. Here's what I get in my console:

iex(1)> Gettext.known_locales(CoreWeb.Gettext)
["en"]
iex(2)> Core.Cldr.known_locale_names()
[:en]

Every other assumption was correct.
