New-MgGroup not working using BodyParameter (asking for mailEnabled value despite being set)

[cyrkin]

Describe the bug

I am trying to create a new Microsoft 365 Group (before converting it to a Teams team).

I am trying to create the group using the New-MgGroup Cmdlet along with the -BodyParameter parameter, especially to select the group owner.

The same code used to work in version 2.25 and below, suddenly stopped working in 2.26.1. I installed v2.25 back and it works again with this version.

Expected behavior

PS> New-MgGroup  -BodyParameter $params

DisplayName            Id                                   MailNickname              Description                                                                            GroupTypes
-----------            --                                   ------------              -----------                                                                            ----------
TEST ORG 123 #groupId# test-org-123 test {Unified}

How to reproduce

$params = @{
    DisplayName = "TEST ORG 123"
    MailEnabled = $False
    MailNickName = "test-org-123" 
    SecurityEnabled  = $True
    GroupTypes = "Unified" 
    Description = "Test"
}
New-MgGroup -BodyParameter $params

Throws the below error :

New-MgGroup : A value is required for property 'mailEnabled' of resource 'Group'.

SDK Version

2.26.1

Latest version known to work for scenario above?

2.25

Known Workarounds

It works this way :
New-MgGroup @params

But then I can't use the following parameter in the set :

"[email protected]" = @(
    "https://graph.microsoft.com/v1.0/users('#userId#')"
)
