Hi MustangProgrammer​,

 

The format of your claim is incorrect, which based on version 2.30.0 of the commandlet does indeed show up in the error:

 

 

 

The specific issue is you haven't provided the key-value pair correctly, where it is supposed to be in the format of "ID":"attributeName". Here's the correct format:

 

$params = @{
    definition = @(
        '{"ClaimsMappingPolicy":{"Version":1,"IncludeBasicClaimSet":"false","ClaimsSchema":[{"Source":"user","ID":"onpremisesssamaccountname","SamlClaimType": "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name"}]}}'
    )

    displayName = "ClaimTest"
}

 

Which is then accepted by Graph, as demonstrated below:

 

 

Cheers,

Lain
