Hi all,Having an issue in Fabric Data Pipelines where trying to invoke a pipeline using a service principal connection is failing with:Error code 2015Failure type User configuration issueDetails Fabric activity failed. 'An item with the same key has already been added.' They run fine when using an OAuth connection tied to my account, however I would like to use the service principal. Any idea why this is happening? There is another connection (a Power BI Semantic Model connection) tied to that service principal, but removing that did not seem to help.

Hi Creykish , Thanks for reaching out to the Microsoft Fabric Community forum. The SPN authentication type currently supports these data sources: Azure Data Lake Storage Azure Data Lake Storage Gen2 Azure Blob Storage Azure Synapse Analytics Azure SQL Database Dataverse SharePoint online Web Please verify if you are using unsupported data source which may be resulting in the error . I hope this information helps. Please do let us know if you have any further queries.Thank you
