win_dsc: failed when used with psrp connection and Windows CJK locale about ansible.windows

[jborean93]

I was finally able to replicate this problem and have a PR which should solve it #244. The issue occurs when there is a mismatch between the UI Culture and the one the PSDesiredStateConfiguration was installed with. Because the psrp connection forces the locale to be en-US you were having a failure where PSDesiredStateConfiguration was trying to load data for en-US when the resources only existed for ja-JP.

What the changes in #244 have done is to temporary change the UI Culture to the installed culture so the import process runs properly before continuing on as normal.

I'm not sure that proposed fix fixes win_dsc, the error here is that the Get-DscResource cmdlet was found in the PSDesiredStateConfiguration module but PowerShell couldn't load it from some reason.

Try running this task to see if it gives you any more errors as to why it couldn't be loaded.

I tried your idea and it didn't change the win_dsc message.

win_template, win_copy and win_service succeed in psrp.

I think this is not a win_dsc problem, although I've only encountered this error with win_dsc at the moment.
In some cases, the psrp response contains non-English messages.
I think psrp.py is not handling it properly.

In some cases, the psrp response contains non-English messages.

That may be the case but the error message you are getting back from win_dsc is

The 'Get-DscResource' command was found in the module 'PSDesiredStateConfiguration', but the module could not be loaded. For more information, run 'Import-Module PSDesiredStateConfiguration'.
At line:332 char:21
+ $module_versions = (Get-DscResource -Name $resource_name -ErrorAction ...
+                     ~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Get-DscResource:String) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : CouldNotAutoloadMatchingModule

It's saying that the cmdlet was found but for some reason the PSDesiredStateConfiguration module could not be loaded. The win_shell example I asked you to try shows that Import-Module works so something else is having issues. Can you try the following 2 tasks

- win_shell: |
    Import-Module PSDesiredStateConfiguration -Verbose
    Get-DscResource -Name xWebsite -Verbose

- win_shell: |
    Get-DscResource -Name xWebsite -Verbose

It might also be a good idea to try using raw instead of win_shell for those 2 examples just to imitate the same context that psrp runs a module in.
