ArgumentException with locale sk_SK when only Humanizr.Core is installed

[nmilcoff]

Related to #647.

I'm hitting the issue on a Xamarin.iOS / Xamarin.Android app that only has the Humanizer.Core package installed. It is crashing for a user whose locale is sk_SK.

Exception: ArgumentException: The resource object with key 'DateHumanize_MultipleHoursAgo' was not found.

Stacktrace:

Humanizer.Localisation.Formatters.DefaultFormatter.Format(System.String resourceKey, System.Int32 number) in <3d8682191b624514bac93fecdf828edb#d241c975ca0c55d1909ef6d5e5b9b762>:0

I can also confirm adding the Humanizer package solves the issue.

[clairernovotny]

If that's the case, then I'm guessing there's a Xamarin/Mono bug with resource fallbacks to the neutral (en-us) culture.

In general, I would always recommend using Humanizer directly since that contains all of the localizations.

[pfedotovsky]

Same issue here for Xamarin.Forms. Humanizer package is installed to .NET Standard and iOS/Android projects. But some users get the

ArgumentException: The resource object with key 'DateHumanize_MultipleHoursAgo' was not found.

I have one report from the field with this exception. I only have the Humanizer.Core including some other localized packages. Report happened from a phone configured for Polish which is not part of my included packages.

This is still broken. https://cdn.discordapp.com/attachments/704786002572738591/714542256429727854/Screenshot_20200525_231534.jpg https://github.com/rayshift/translatefgo/commit/f3613b3aa6d1a3231ff2c21a6b4e0a5827c79dd4#diff-b3c60ceedea4da7e766ceaa93d89c40dR290

I got same problem with .NET Core 3.1, reproducing easily enough with some DateTime values and Humanize(utcDate: false). Computer culture Russian and installed packages are: Humanizer.Core 2.8.26 and Humanizer.Core.ja 2.8.26 . As workaround i set app current culture to English (If it not Japanese).

[Filipowicz251]

I can concur. Have the same problem with Polish translation. Xamarin on Android.

Previously I did use Humanizer.Core 2.8.26 + Humanizer.Core.pl 2.8.26 There was an exception thrown. I've changed to Humanizer 2.8.26 - the problem still occurs.

I am using Xamarin Android (Andorid 9.0 (Api Level 28 - Pie)) with library as .NET Core 2.1

I am using .Humanize(utcDate: false);

Just had the same – or similar – error thrown in my ASP.NET Core application. What's weird, is that it was perfectly fine just a minute ago, but restarting the app caused the error to star occurring.

Edit: using .Humanize(culture: CultureInfo.InvariantCulture) fixed the issue.

We are experiencing the same issue in xamarin forms for Polish language. Only Android - IOS works fine. Is there any possible way to fix this?

[clairernovotny]

This issue is external as it has to do with resource localization/fallback. Please open an issue on https://github.com/dotnet/runtime (and feel free to link back to here/reference here).

[KSemenenko]

so, @clairernovotny there is no way to fix it for Android?

[ivmirx]

My workaround is calling .Humanize(culture: CultureInfo.InvariantCulture) for the languages I did not include. I'm checking for those with CultureInfo.CurrentUICulture.TwoLetterISOLanguageName.

[hazzik]

I have found out why that happens.

The error is sadly a bit misleading. Consider these code excerpts:

https://github.com/Humanizr/Humanizer/blob/606e958cb83afc9be5b36716ac40d4daa9fa73a7/src/Humanizer/Localisation/Formatters/DefaultFormatter.cs#L131-L138

https://github.com/Humanizr/Humanizer/blob/606e958cb83afc9be5b36716ac40d4daa9fa73a7/src/Humanizer/Localisation/Formatters/CzechSlovakPolishFormatter.cs#L5-L20

So, the actual missing resource keys are missing, they just show up invalid in the exception text. The missing ones are those with _Paucal suffix - there are no such resource keys.

Generally, I'd say that it's a global issue. English (fallback) resources don't contain special, culture-specific-suffix additions. I have not come up with a good, quick fix for this. We'd probably need to somehow detect the fallback is used and retry with an unsuffixed resource key.
