Azure users with empty names get an error upon login

[oanat]

Some Azure users got the following error when trying to login:
You will be redirected to the OAuth provider for authorization. An error occurred during login with an OAuth provider. Please contact the administrator or XWiki support. Trouble at fetchIdentityDetails.

More details concerning the error from the logs:
Caused by: java.lang.NullPointerException: null at com.xwiki.azureoauth.AzureADIdentityOAuthProvider$MSADIdentityDescription.<init>(AzureADIdentityOAuthProvider.java:433) at com.xwiki.azureoauth.AzureADIdentityOAuthProvider$MSADIdentityDescription.<init>(AzureADIdentityOAuthProvider.java:423) at com.xwiki.azureoauth.AzureADIdentityOAuthProvider.fetchIdentityDetails(AzureADIdentityOAuthProvider.java:330) ... 217 common frames omitted

@polx mentioned this seems to be caused by null values for firstname or surname from https://github.com/xwikisas/integration-azure-oauth/blob/master/api/src/main/java/com/xwiki/azureoauth/AzureADIdentityOAuthProvider.java#L433

1.2-M1 has been released to address this bug.
It only contains translations simplifications otherwise.
Could you try it please?
Here is the suffix of the URL to request it:

Considered fixed in 1.2
