Executing AML pipeline from Fabric pipelines

Anonymous — Thu, 05 Feb 2026 15:30:11 GMT

I'm struggling to execute Azure Machine Learning pipelines from Fabric pipelines. The connection was established using Service Principal (granting contributor role to Fabric Service Principal in the Azure Machine Learning workspace previously). When I try to "Test connection" it shows the following message:

One interesting thing is that I can see the pipelines that I published previously in Azure Machine Learning (such us inference-pipeline-2.0) but when I try to execute the Fabric pipeline I receive this error message when the Fabric pipeline gets to the Execute Machine Learning:

Request sent to Azure ML Service for operation 'validateWorkspace' failed with http status code 'Unauthorized'. Error message from Azure ML Service: '{"error":{"code":"InvalidAuthenticationTokenAudience","message":"The access token has been obtained for wrong audience or resource 'https://ml.azure.com'. It should exactly match with one of the allowed audiences 'https://management.core.windows.net/','https://management.core.windows.net','https://management.azure.com/','https://management.azure.com'."}}'.

I saw a similar Ticket opened here from 2024 but nobody seemed to solve it. Thanks.
