`type.locale_default_unsupported`

Default locale is not a supported one.

Area 10, Configuration; not declinable; the next step is usually the agent's.

example

locales {    default: Locale.fr_fr    supported: [Locale.en_gb]}

jadpo checkcheck failed: 1 error, 1 file

error The default Locale.fr_fr isn't a supported locale

--> main.jadpo:2:14

  |2 |     default: Locale.fr_fr  |              ^^^^^^^^^^^^ not in `supported:`3 |     supported: [Locale.en_gb]  |                -------------- the supported locales

reason: The default is what a request with no usable Accept-Language is given, and formatting and translations accept only the supported locales, so the default has to be one.
next: Add Locale.fr_fr to supported:, or choose a default that is listed (agent)
