Hi SGRS
The error message suggests that connectivity is failing at some point. Can you try the steps below to troubleshoot and narrow down the cause of the issue?
- Basic refresh : Sign out/in, try again in another browser or in a private window.
- Quick test : In the same workspace, create a brand-new dataflow with just. Save it. If even that fails, it’s a workspace/capacity problem, not your query.
= #table({"Test"}, {{1}})- Check credentials : In dataflow settings, re-authenticate every data source. If you’re on a gateway, make sure it’s online and mapped right.
- Clone the dataflow : Export to .json (or Save As in Gen2) and re-import. Sometimes the current instance just gets stuck.
- Undo the last step : If the error started right after a change, remove that step and see if it opens. Large merges or certain Web.Contents calls can cause this.
If none of that works, grab the Request ID, Activity ID, and timestamp from the error and send it to Microsoft Support they can check the backend logs.
