EventStream Azure Service Bus as Source | Connect Exception with on-prem data gateway connection

Hi to-know-better ,

Thank you for engaging with the Microsoft Fabric Community. Eventstream couldn’t read the Shared Access Policy Name correctly from your connection settings. This issue often arises when setting up the connection via Manage Connections and Gateways, where required fields like the policy name may not be passed through properly.

Please check the following

1. Verify that the Shared Access Key Name (policy name) is entered correctly

2. Ensure the key value is accurate

3. Confirm your on premises data gateway is installed and configured correctly

Additionally, the Eventstream UI currently doesn’t allow you to select a gateway directly when configuring an Azure Service Bus source. This has been noted by other users, although it’s not yet documented.

Lastly, please note that Service Principal authentication is not supported for ASB connections in Eventstream at this time. If you’d like this feature, you can suggest or vote for it in the Fabric Ideas portal.
