Getting "Invalid enum value unknown" when trying to update mailboxSettings

[antoniom]

Describe the bug

I am trying to update the mailboxSettings of a user via the following script

$mailboxSettings = new MailboxSettings();

$automaticRepliesSetting = new AutomaticRepliesSetting();
$automaticRepliesSetting->setStatus(new AutomaticRepliesStatus(AutomaticRepliesStatus::DISABLED));
$automaticRepliesSetting->setExternalAudience(new ExternalAudienceScope(ExternalAudienceScope::ALL));
$automaticRepliesSetting->setExternalReplyMessage("I am out of office with limited access to email.");
$automaticRepliesSetting->setInternalReplyMessage("I am out of office with limited access to email.");
$mailboxSettings->setAutomaticRepliesSetting($automaticRepliesSetting);

$response = $msGraph
    ->getClient()
    ->users()
    ->byUserId(<USERID>)
    ->mailboxSettings()
    ->patch($mailboxSettings)
    ->wait();

And I receive the following exception

Exception 'InvalidArgumentException' with message 'Invalid enum value unknown'

in /var/www/html/vendor/microsoft/kiota-abstractions/src/Enum.php:57

MailboxSettings.php(121) -> points to UserPurpose which is a readonly value and shouldn't be set.

If a try to set it
e.g.

$mailboxSettings->setUserPurpose(new UserPurpose(UserPurpose::ROOM));

I get the error, the property 'userPurpose' was specified but is not supported with this request.

Expected behavior

The request to succeed without having to call setSserPurpose property

How to reproduce

Execute the above script

SDK Version

2.12.0

Latest version known to work for scenario above?

No response

Known Workarounds

Use msgraph-sdk-php-core and execute the request manually ie

$httpClient = GraphClientFactory::createWithConfig($config);
$response = $httpClient->patch(
    '/v1.0/users/<USER-ID>/mailboxSettings',
    [
        'json' => [
            'automaticRepliesSetting' => [
                "externalAudience"=> "all",
                "status" => "disabled"
            ]
        ]
    ]
);

@antoniom, thank you for raising this issue. After investigations, I found out that the service is returning an undefined/undocumented value (unkown) for the property userPurpose.

Based on the documentation here https://learn.microsoft.com/en-us/graph/api/resources/mailboxsettings?view=graph-rest-1.0#userpurpose-values, the value unkown is not among the list of documented enums.

It is also not specified in the OpenAPI file used to generate this particular service in the SDK.

Unfortunately for API related issues/questions we are not best placed to give an answer. Kindly raise an issue here https://developer.microsoft.com/en-us/graph/support so that the API owner can respond to it.
