Accessing Service Bus Across Subscriptions

[umashankarsharma]

We are trying to create a standard logic app with (When messages are available in a topic subscription (peek-lock)) and trying to access a service bus that is in different subscription using managed identity. VNET is enabled in this case. But we are getting UnAuthorized error as below.

Failed to create connection: {"error":{"code":"ServiceProviderOperationFailed","message":"Service request failed.\r\nStatus: 401 (Unauthorized)\r\n\r\nContent:\r\n401Manage,EntityRead claims required for this operation. TrackingId:23bd65c8-d3dc-4c80-8671-f8c4513e6f69_G37, SystemTracker:XXXXX.servicebus.windows.net:$Resources/queues, Timestamp:2023-09-29T16:44:18\r\n\r\nHeaders:\r\nTransfer-Encoding: chunked\r\nServer: Microsoft-HTTPAPI/2.0\r\nStrict-Transport-Security: REDACTED\r\nDate: Fri, 29 Sep 2023 16:44:18 GMT\r\nContent-Type: application/xml; charset=utf-8\r\n"}}

Any ideas or information to get around this. Service Bus are on different Subscription , but we plan to build SLA in another subscription and do not want to move resources across.
