    Hi @jaso223 ,

    Welcome to Microsoft Q&A forum and thanks for reaching out here.

    By looking at the error message my understanding is that you may have used either service principal or managed identity authentication in your Azure blob storage account liked service. Please correct if I'm wrong.

    Ref doc: ADF mapping data flow - User-assigned managed identity authentication

    If your blob account enables soft delete, system-assigned/user-assigned managed identity authentication is not supported in Data Flow.

    Ref doc: Error code: DF-Blob-FunctionNotSupport

    Azure Blob Storage events, soft delete or automatic snapshot is not supported in data flows if the Azure Blob Storage linked service is created with service principal or managed identity authentication.

    Solution: Hence to overcome the issue, disable Azure Blob Storage events, soft delete or automatic snapshot feature on the Azure Blob account, or use account key authentication to create the linked service.

    Below is how you can disable soft deletes. User's image

    Hope this info helps.
