syntax.locales_unknown_option

Locales declaration has no such option.

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

There is no unsupported: setting (see "Locales"). A misspelt option (suported:) is reported the same way, with the nearest name:

example
locales {    default: Locale.en_gb    supported: [Locale.en_gb]    unsupported: Locale.fr_fr}
text
error: `unsupported` isn't an option of `locales` --> main.jadpo:4:5  |4 |     unsupported: Locale.fr_fr  |     ^^^^^^^^^^^ unknown option  reason: There is no `unsupported:` setting. A request field typed `Locale` is decoded like any enum, so a tag the application doesn't support is an `invalid_value` failure, and choosing a language from an `Accept-Language` header falls back to `default:`.  next: Remove `unsupported:` (agent)  rule: syntax.locales_unknown_option  help: https://jadpo.dev/docs/errors/syntax.locales_unknown_optioncheck failed: 1 error, 1 file
