Same issue for me. In my case, the source table was created via Copy Activity in a pipeline. I deleted and re-created the table and the notebook worked for the first times, but then started to fail again... so frustrating.

Have you found a fix? I have the exact issue with Data Copy, always good at the first few attempts then always failed after that. This really make it very hard to adopt Fabric 😞

    From my dealing with MS Support. It seems that updating the data gateway to the latest version stopped the issue from recurring. Give it a try.

      Thanks, my gateway is March 2024, let me try to upgrade it to May 2024 then see if the issue is gone.

    Did updating the gateway work? I tried that but the issue persists. Wondering if there may be any other tricks or steps.
