Receiving 403 when accessing Service Bus REST API with incorrect Subscription / Resource Group

[Kaegun]

Description

When calling the Service Bus REST API (https://learn.microsoft.com/en-us/rest/api/servicebus/) with an incorrect SubscriptionId or ResourceGroup parameter, I receive a 403 error back. I spent far too much time chasing authentication failures before realizing the misconfigured SubscriptionId/ResourceGroup.

Actual Behavior

1. Call Service Bus REST operation - POST https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.ServiceBus/namespaces/{namespaceName}/topics/{topicName}/authorizationRules/{authorizationRuleName}/ListKeys?api-version=2021-11-01
2. Use an incorrect value for subscription or resource group.
3. Receive 403 response.

Expected Behavior

1. Call REST operation - POST https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.ServiceBus/namespaces/{namespaceName}/topics/{topicName}/authorizationRules/{authorizationRuleName}/ListKeys?api-version=2021-11-01
2. Use an incorrect value for subscription or resource group
3. Receive 404 response
