Oh I just noticed this as well also v9.0.1 🙈
It would be great to get this fixed as we soon need to invite content editors, but currently we need to create users manually or enabled the invited user afterwards.

Looks like the error occurs because 9.0.1 doesn't set the sender address to the back-office user that's sending the invite anymore (which was a bug, as that might not be a valid sender address for the configured SMTP settings): #11266.

Even though Umbraco Cloud adds a fallback for sending invitations without having SMTP configured, this doesn't expect the null value, hence the Value cannot be null error.

You can work-around this issue by at least providing the Umbraco:CMS:Global:Smtp:From setting as shown in the example on https://our.umbraco.com/documentation/umbraco-cloud/Set-up/SMTP-settings/. If you want to send out emails, you will need to configure the SMTP server anyway...

Yeah, except when the client don't use form or similar to send emails, but only need the feature to invite other users. Previous this required SMTP to be configured, but in a V8 version this changed, so the invite user button always was shown on Umbraco Cloud environments and thus didn't required further SMTP configuration to use the invite user flow.

Not sure if it is related to this: #11575

@ronaldbarendse it doesn't seem to be enough just providing the Umbraco:CMS:Global:Smtp:From setting.

It still throw this exception:

False MSAL 4.35.1.0 MSAL.NetCore .NET 5.0.9 Microsoft Windows 10.0.14393 [11/14 14:20:05.38 - 696e8355-dae8-4ab7-a6e4-132a6a82d505] Exception type: Microsoft.Identity.Client.MsalUiRequiredException , ErrorCode: user_null HTTP StatusCode 0 CorrelationId at Microsoft.Identity.Client.Internal.Requests.Silent.SilentRequest.ExecuteAsync(CancellationToken cancellationToken) at Microsoft.Identity.Client.Internal.Requests.Silent.SilentRequest.ExecuteAsync(CancellationToken cancellationToken) at Microsoft.Identity.Client.Internal.Requests.RequestBase.RunAsync(CancellationToken cancellationToken)

Update: Okay, it actually does seem to work now. Not sure if something was cached on production/live for some time.
