Power BI Refresh Error:
Dataflow failures in Premium workspaces
What does this error mean?
Certain data connectors are not supported for dataflows running in Power BI Premium workspaces, causing refresh failures with an expression error indicating the connector module cannot be resolved. The available connector set for Premium dataflows differs from standard Power BI Desktop.
Common causes
- 1A dataflow uses a connector that is supported in Power BI Desktop but not certified or available for Premium workspace dataflows
- 2A custom or community connector referenced in the dataflow is not deployed or registered in the Premium environment
- 3The connector module name has changed or is missing a required module reference in the Premium dataflow runtime
- 4Migrating a dataflow from a shared workspace to a Premium workspace without verifying connector compatibility
How to fix it
- 1Step 1: Note the exact connector name from the error message (e.g., 'Expression.Error: The import "<connector name>" matches no exports') and check Microsoft's official list of supported connectors for Power BI dataflows in Premium workspaces.
- 2Step 2: If the connector is unsupported in Premium, evaluate alternative supported connectors that can reach the same data source (e.g., using ODBC or OData instead of a proprietary connector).
- 3Step 3: If the data ingestion cannot be done via a supported connector, consider performing the transformation in Power BI Desktop or Azure Data Factory instead and importing the result into the dataflow.
- 4Step 4: For custom connectors, work with your Power BI admin to register and deploy the connector in the Premium capacity environment if supported.
- 5Step 5: If no workaround is available, file a support ticket with Microsoft at powerbi.microsoft.com/support to request connector support or clarification on the Premium roadmap for that connector.
