Power BI Refresh Error:
ADLSGen2OperationFailed

What does this error mean?

An ADLS Gen2 operation failed in ADF or Fabric. This error wraps a storage-level inner error — check the inner message for the specific cause and fix.

Common causes

  • 1The error wraps a more specific Azure Data Lake Storage Gen2 error — check the inner message for details
  • 2The service principal or managed identity lacks sufficient permission to access ADLS Gen2 (Forbidden in inner message)
  • 3The integration runtime's IP address is not allowed by the ADLS Gen2 storage account firewall (connection forcibly closed)
  • 4Transient Azure ADLS Gen2 service issue (InternalServerError in inner message)
  • 5Using an ADLS Gen2 linked service to connect to an Azure Blob Storage account that has BlobStorageEvents or SoftDelete enabled

How to fix it

  1. 1Check the inner error message in ADLSGen2OperationFailed — it contains the specific storage error code and cause
  2. 2If the inner message contains 'Forbidden': grant the service principal or managed identity the 'Storage Blob Data Contributor' (write) or 'Storage Blob Data Reader' (read) RBAC role on the container
  3. 3If the inner message says 'connection was forcibly closed': add the ADF integration runtime IP addresses to the storage account firewall allowlist
  4. 4If the inner message says 'This endpoint does not support BlobStorageEvents or SoftDelete': either upgrade the Azure Blob Storage account to ADLS Gen2, switch the linked service to use the Azure Blob Storage connector, or disable Blob storage events and soft delete on the storage account
  5. 5For transient errors (InternalServerError): retry the operation; if it persists, contact Azure Storage support with the request ID from the error message
