To Reproduce:

Steps to reproduce the behavior. Note that argument values have been redacted, as they may contain sensitive information.

• Put any pre-requisite steps here… When running az ad app update --id <name> --app-roles <json array> with the below as the json content

    [
        {
            "allowedMemberTypes": [
                "Application"
            ],
            "description": "TestRol",
            "displayName": "TestRole",
            "id": "c94e8335-ab55-4589-ba7d-075b035605c5",
            "isEnabled": true,
            "origin": "Application",
            "value": "TestRole"
        }      
    ]

the command executes successfully but the App Role is NOT created\viewable in either the portal or via CLI.

If I add a second app role to the Json file

    [
        {
            "allowedMemberTypes": [
                "Application"
            ],
            "description": "TestRol",
            "displayName": "TestRole",
            "id": "c94e8335-ab55-4589-ba7d-075b035605c5",
            "isEnabled": true,
            "origin": "Application",
            "value": "TestRole"
        },
        {
            "allowedMemberTypes": [
                "Application"
            ],
            "description": "TestRol2",
            "displayName": "TestRole2",
            "id": "c94e8335-ab55-4581-ba7d-075b035605c5",
            "isEnabled": true,
            "origin": "Application",
            "value": "TestRole2"
        }         
    ]

The command executes successfully and both app roles are created

Expected Behavior

App Roles in App Registration should be created regardless of Array size (in this case 1 entry in the array)

Yeah dynamic typing in Powershell got me - two entries makes it an array…

Looks like you didn’t surround the app role with square brackets:

'--app-roles', '{\n  "allowedMemberTypes": [\n    "Application"\n  ],\n  "description": "TestRol",\n  "displayName": "TestRole",\n  "id": "c94e8335-ab55-4589-ba7d-075b035605c5",\n  "isEnabled": true,\n  "origin": "Application",\n  "value": "TestRole"\n}',

Could your surround it with [] and try again?
