Notebook error reading delta table

[jcvega]

I created a parquet file/delta tables using DataFlow Gen2.  Now, I am trying to read it from a Notebook, but, I am receiving this error> Mismatched minReaderVersion and readerFeatures.  Someone knows the cause of the issue?

I'm having the same issue. Difference is the table wasn't created via Dataflow Gen2 but instead written into Lakehouse via the same notebook. The issue seems to creep randomly. Most of the time it doesn't come up but from time to time it comes back.

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 😞

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

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.
