The client xxx with object id xxx does not have authorization to perform action Microsoft.Resources/subscriptions/resourcegroups/write' over scope

Question

I am trying to create a Resource Group dynamically using Azure Management SDK Here are my azure configuration details

subscription=<private-data>
client=<private-data>
key=<private-data>
tenant=<private-data>
managementURI=https://management.core.windows.net/
baseURL=https://management.azure.com/
authURL=https://login.windows.net/
graphURL=https://graph.windows.net/

Here is code for creating Resource

// Credentials
AzureCredentials credentials = new AzureCredentialsFactory()
    .FromFile("azureauth.properties");
string resourceName = GetRandomString();

// Create Azure Instance
var azure = Azure
        .Configure()
        .Authenticate(credentials)
        .WithDefaultSubscription();

// Create a Resource Group
azure.ResourceGroups
        .Define(resourceName)
        .WithRegion(Region.USWest)
        .Create();

The error that I got is:

The client 'ae8bc2ea-9680-4f66-934c-ad40b82c30ac' with object id 'ae8bc2ea-9680-4f66-934c-ad40b82c30ac' does not have authorization to perform action 'Microsoft.Resources/subscriptions/resourcegroups/write' over scope '/subscriptions/e9d61100-a82a-48ca-b6f8-51b06a1eebe6/resourcegroups/5oxjhjic'.

I have followed steps specified on https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-create-service-principal-portal
As well as I am trying with my Global Administrator account

Solution

you cant be trying with global administrator, obviously. you need to go to you subscription and grant objectid 'ae8bc2ea-9680-4f66-934c-ad40b82c30ac' contributor permissions (easy way) or create a custom role (or figure predefined role) that meets your needs.

you can use portal to do that or azure powershell:

New-AzRoleAssignment -ObjectId 'ae8bc2ea-9680-4f66-934c-ad40b82c30ac' -Scope '/subscriptions/e9d61100-a82a-48ca-b6f8-51b06a1eebe6' -RoleDefinitionName contributor

the equivalent Azure CLI command is:

az role assignment create --assignee-object-id ae8bc2ea-9680-4f66-934c-ad40b82c30ac --scope subscriptions/e9d61100-a82a-48ca-b6f8-51b06a1eebe6 --role contributor
