Fabric pipeline error with semantic model

Hi stiggrr87 , Thank you for reaching out to the Microsoft Community Forum.

This usually happens because the pipeline activity cannot retrieve the current table metadata from the semantic model. The Semantic model refresh activity first tries to list the tables in the dataset (ListTables). If that call fails, Fabric cannot show the table list and you may see errors like “Table is missing” or “Could not connect to WebConnection – ListTables”. This often appears after the model structure changes (tables deleted or recreated).

The pipeline itself does not store the table structure, but it depends on the metadata returned by the semantic model in the service. If the dataset was overwritten or republished, the activity may still be pointing to outdated metadata. Reselect the semantic model or recreate the refresh activity, which forces Fabric to fetch the current schema again. Also confirm the dataset refresh works directly in Power BI Service, since the pipeline uses the same refresh APIs.
