We have this error message DM_GWPipeline_Gateway_CanceledError since a couple of days

[vinny1986]

We've been having this issue since a couple of days.

The error message is as follow:

{"error":{"code":"DM_GWPipeline_Gateway_CanceledError","pbi.error":{"code":"DM_GWPipeline_Gateway_CanceledError","parameters":{},"details":[],"exceptionCulprit":1}}} Table:

We upgraded our on premise data gateway to the lastest version today and it still gives this error message on scheduled and manual refreshes.

We're experiencing this issue as well, with 4 or 5 semantic models (out of 9).

• Intermittant scheduled refresh failures for semantic models that have never had issues with scheduled refreshes before.
• Manual refresh seems to work all of the time.
• Some refresh schedules will occasionally work.
• The refresh schedule is lean, with no more than 1 refresh in a 24 hour period per semantic model.
• Gateway status is reporting good.

Our specific error for all semantic model failures:

{"error":{"code":"DM_GWPipeline_Gateway_CanceledError","pbi.error":{"code":"DM_GWPipeline_Gateway_CanceledError","parameters":{},"details":[],"exceptionCulprit":1}}}

We have updated the Gateway (March 2025), Restarted the server, Restarted the Gateway, Assigned more resources to Gateway server. Still seeing issues.

Seems Microsoft have acknowleged the error:

I am reluctant to roll back to the September Gateway version. Will wait until the next Gateway update.

Hi @vinny1986,

Thank you for reaching out to the Microsoft Fabric Community Forum.

We sincerely apologize for the inconvenience. After reviewing the issue of receiving the error message ‘DM_GWPipeline_Gateway_CanceledError’ for the past few days, we have outlined some steps that might help resolve the issue:

It looks like the error message ‘DM_GWPipeline_Gateway_CanceledError’ is related to Power BI and occurs when a task is cancelled during the data refresh process. This issue may persist even after upgrading the on-premises data gateway to the latest version.

• The error frequently occurs when a task is cancelled during the data refresh process, often due to network issues, server overload, or conflicts with other operations.
• Please ensure there are no network issues or server overloads that could be causing the task cancellation. Review the gateway logs for any errors that might provide further details.
• Clear the cache and all permissions, then sign in again and refresh the report in Power BI Desktop. Publish the report to a different workspace and check if the issue persists.
• Additionally, create a new sample test report with the same data, refresh it in Power BI Desktop, and publish it to a newly created workspace in Power BI Service to see if the issue is resolved.
• Ensure that the gateway and data sources are correctly configured and meet the minimum requirements. Sometimes, moving the gateway to a different server or updating the server can help resolve the issue.
• Some users have resolved the issue by restarting the on-premises gateway services and the servers they are running on. Additionally, checking the source systems for any recent changes and ensuring they are functioning correctly can be beneficial.

We installed the September version of the gateway and it now works for our refresh.

Hi @vinny1986 ,

The DM_GWPipeline_Gateway_CanceledError occurs when the Power BI On-Premises Data Gateway cancels a query execution. This usually happens due to:

• Gateway connection issues
• Long-running queries causing timeouts
• High data volume affecting performance

If your scheduled and manual refreshes are failing, try these steps:

1. Check Gateway Status → Ensure it's online in Manage Gateways.
2. Increase Timeout → Admin Portal > Tenant Settings > Dataset Default Timeout.
3. Optimize Queries → Reduce data volume or improve SQL query performance.
4. Check Logs → Review On-Prem Gateway Logs for detailed errors.
5. Restart Gateway → Restart the service in Gateway Settings.
