Cannot send email with Send-MgUserMail after updating to 2.26.0

[rdvanto2]

Describe the bug

Unable to send mail with version 2.26.0, after upgrading i get this error message:

Send-MgUserMail_Send: Invalid character after parsing property name. Expected ':' but got: ". Path
'Message.ccRecipients[0].emailAddress', line 8, position 28.

Expected behavior

I would like the mail to send without error. This works fine if version 2.25.0

How to reproduce

execute Send-MgUserMail with users in the CcRecipients. I am running powershell 7.5.0 on Redhat Linux

$params = @{
message = @{
subject = "Meet for lunch?"
body = @{
contentType = "Text"
content = "The new cafeteria is open."
}
toRecipients = @(
@{
emailAddress = @{
address = "[email protected]"
}
}
)
ccRecipients = @(
@{
emailAddress = @{
address = "[email protected]"
}
}
)
}
saveToSentItems = "false"
}
