get_inventory_summary_marketplac results "Unauthorized" error code

[Biebras]

I have these keys:
REFRESH_TOKEN
LWA_APP_ID
LWA_CLIENT_SECRET

Code:

inventory_client = Inventories(credentials=CLIENT_CONFIG, marketplace=Marketplaces.DE)
inventory = inventory_client.get_inventory_summary_marketplace(marketplaceIds = ["A1PA6795UKMFR9"])

Error: [{'code': 'Unauthorized', 'message': 'Access to requested resource is denied.', 'details': ''}]

Permissions:

When I try to access orders, it works:

order_client = Orders(credentials=CLIENT_CONFIG, marketplace=Marketplaces.DE)
order = order_client.get_orders(CreatedAfter=(datetime.utcnow() - timedelta(days=7)).isoformat())

Any ideas why this request is rejected?

The problem was that when I created the app and generated the refresh key, it had limited permissions. If you check new permissions you need to generate a new refresh key!!!!
