I have few custom directory roles with specific permissions. I attempted to do it from graph but no use, throwing errors.
Is there any other possible way to get that list from Powershell Or CLI.
Get-AzRoleDefinition
Getting all roles, how to add custom role filter for this command?
I tried to reproduce the same in my environment to get the custom roles using PowerShell
Here is the script to get Azure custom roles with Filter.
#import and Install Az Module
Import-Module Az.Accounts
Install-Module -Name Az -Scope CurrentUser -Repository PSGallery -Force
#connect-Azure Account
Connect-AzAccount
#Get All Azure AzRoleDefinition
Get-AzRoleDefinition
Get-AzRoleDefinition -Name Reader
#Get Custom Roles
Get-AzRoleDefinition -Custom |? {$_.IsCustom -eq $true}| FT Name,IsCustom,Id
Output with Filter command.
