Cannot access to AML batch endpoints from Fabric pipelines
Hi Anonymous ,
Thank you for engaging with the Microsoft Fabric Community. Based on the error message, it looks like the Web activity request is not reaching the Azure ML endpoint. The issue seems to be happening on the Fabric side before the call is actually sent, which is why the status shows as NA – Unknown along with a client side exception.
Since the AML workspace is already open to public access, this usually points to a configuration or connectivity issue in the Web activity. Could you please check the following
1. Make sure the complete endpoint URL is being used, including the /jobs path and API version (if required).
2. Verify that the Authorization header is added correctly.
3. Try calling the same endpoint using Postman or a notebook to confirm whether it works outside Fabric.
4. If possible, test calling a simple public API from the same Web activity to validate outbound connectivity.
I hope this clarifies the situation. If I’ve misunderstood any part of your situation, please let us know.
