Windowscommunitytoolkit: Unable to translate English to Japanese

[zipswich]

Describe the bug

Unable to translate English to Japanese

• [x] Is this bug a regression in the toolkit? If so, what toolkit version did you last see it work:
  Not sure which is the last working version. At least a version of last year worked.

Steps to Reproduce

Steps to reproduce the behavior:
Run the following code:
await TranslatorService.Instance.TranslateAsync("test", "en", "jp").ConfigureAwait(true);

Exception details:

Newtonsoft.Json.JsonSerializationException
  HResult=0x80131500
  Message=Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.IEnumerable`1[Microsoft.Toolkit.Services.MicrosoftTranslator.TranslationResponse]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.
To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List<T>) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.
Path 'error', line 1, position 9.

Thanks for filing the bug @zipswich, did it work with other languages you tried still? Wondering if the response from the server has changed...

@marcominerva any thoughts?

[marcominerva]

The exception says that JSON has an unexpected format. In fact, it could be caused by a change in the response from the server. Let me double check, I'll keep you informed about any progress.

[zipswich]

It works perfectly for every other language that I have tested (cs, de, es, et, fr, it, ko, nl, pl, pt, ru, sl, uk, zh).

Thanks for looking into this. Please feel free to let me know if I can assist in any way.

[marcominerva]

The correct language code for Japanese is ja, as returned by the GetLanguageNamesAsync method:

await TranslatorService.Instance.TranslateAsync("test", "en", "ja").ConfigureAwait(true);

[zipswich]

Thanks a lot. Very sorry for the mistake.
I am really surprised. Our hardware partner requested and apparently tested the Japanese translation using "values-jp" folder in an Android app, and this is why "jp" was used.

[Kyaa-dost]

@marcominerva Thanks so much for looking into this. @zipswich so are we all clear on this?

[zipswich]

Yes. I am all set now.
I wanted to add that the reason that I thought it worked before is that I had another app the did Japanese translation last year, but it used the retrieved language code, and I thought it was the same as "jp".
May I make a suggestion: dump the response in the exception message when the json deserialization generates an exception.
