Power BI Refresh Error:
DF-MSSQL-ExportErrorRowFailed

What does this error mean?

The data flow is configured to redirect error rows to a file, but that export operation itself failed. This means the error row output path (Azure Blob or ADLS) is inaccessible, the linked service for the error output lacks write permissions, or the output container or folder doesn't exist.

Common causes

  • 1The error row output linked service is not configured or references a non-existent container
  • 2The ADF managed identity lacks write permissions on the error row output storage account
  • 3The folder path for error output contains a typo or was deleted
  • 4The error output linked service credentials have expired or were rotated

How to fix it

  1. 1In ADF Studio, open the Sink transformation > Error row handling tab and check the 'Error row linked service' and output path.
  2. 2In the Azure portal, go to error output storage account and confirm the container and folder path exist.
  3. 3Under Access Control (IAM) for the container, verify the ADF managed identity has Storage Blob Data Contributor.
  4. 4Test connection the error row output linked service to confirm connectivity.
  5. 5If the error row redirect is not essential, temporarily set error handling to 'Skip' to unblock the pipeline while you fix the output path.

Frequently asked questions

Does this error affect all pipeline runs or just the current one?

Depends on the root cause. A persistent misconfiguration fails every run; a transient issue may resolve on retry. Check the run history.

Can this error appear in Azure Data Factory and Microsoft Fabric pipelines?

Yes — the same connector errors appear in both ADF and Fabric Data Factory pipelines.

How do I see the full error detail for an ADF pipeline failure?

In ADF Monitor, click the failed run, then the failed activity. The detail pane shows the error code, message, and sub-error codes.

Will downstream Power BI datasets be affected when an ADF pipeline fails?

Yes — a dataset refreshing after the pipeline will use stale data or fail if the target table was cleared. The Power BI refresh may succeed while serving wrong data.
