Fix Power BI Fabric Pipeline LSROBOTokenFailure Errors
Question details
The user needs to resolve an LSROBOTokenFailure error that prevents a Microsoft Fabric pipeline from executing due to revoked or expired authentication grants.
- Product
- Microsoft Fabric
- Device & OS
- not provided
- Scenario
- Executing a Microsoft Fabric data pipeline.
- Observed behavior
- The pipeline fails with LSROBOTokenFailure and AADSTS50173 errors. Changing owner credentials and basic reauthentication did not immediately resolve the issue.
Ensure you have the necessary administrative privileges in Microsoft Entra ID to update and authorize the affected connection credentials.
Reauthenticate Credentials and Refresh Tokens
Update the pipeline's connection credentials directly to force a refresh of the authentication tokens via Microsoft Entra ID.
The LSROBOTokenFailure and AADSTS50173 errors occur when the background authentication tokens for the pipeline connection expire or are revoked. Simply changing the workspace owner might not refresh the stored token in the connection itself.
Navigate to your Microsoft Fabric workspace and open the settings for the failing data pipeline.
Go to the connections or linked services section where the pipeline authenticates to its specific data sources.
Edit the connection, select the option to reauthenticate, and log in with your updated Microsoft Entra ID administrator credentials.
Save the updated connection settings to generate new authentication tokens, then trigger a manual run of the pipeline to verify the error is resolved.
Analyze Your Exported Data Seamlessly with WPS Office
While Microsoft Fabric manages complex data pipelines in the cloud, you need a robust tool to analyze your final data exports. WPS Office provides a lightweight, highly compatible alternative to Microsoft Office for everyday data analysis and reporting.
- 1. Download WPS Office: Visit the official WPS Office website and download the free installer.
- 2. Install the Software: Run the installer and complete the quick, standard setup process.
- 3. Analyze Data Exports: Open WPS Spreadsheet to easily import, format, and analyze your data pipeline exports.
Frequently Asked Questions
What does the AADSTS50173 error mean in Microsoft Fabric?
This error code indicates that the Microsoft Entra ID (formerly Azure AD) authentication grant has expired or was explicitly revoked, requiring the user to reauthenticate to obtain a new token.
Why didn't changing the pipeline owner fix the LSROBOTokenFailure?
Changing the owner modifies permissions at the workspace level, but it does not automatically refresh or update the cached authentication tokens in the underlying data connections used by the pipeline.
Where can I get help for persistent Fabric pipeline errors?
For specialized Power BI and Fabric troubleshooting, you should post your error details in the Microsoft Fabric Community forums or create a direct support request through your Microsoft 365 admin portal.
