DM_GWPipeline_Gateway_SpooledOperationMissing
Power BI dataset refresh error — what it means and how to fix it.
What this means
The gateway lost the in-progress operation state (the gateway service restarted mid-refresh, or the host VM was cloned after the gateway was installed).
How to fix it
- Check the gateway logs for service restarts.
- Do not clone gateway host machines; install the gateway fresh on each host.
- Apply host patches outside refresh windows, then retry the refresh.
