Error Encountered During Data Factory Pipeline Execution

Hi Chelly 
Thanks for using Fabric Community.
Can you please follow the below steps and retry :

At the leftside of the notebook please click on lakehouses.

Click on Add lakehouse.

Select the lakehouse where the table resides. Attach the lakehouse to the notebook.

Now try to run the pipeline. Please let me know if the issue still persists.

Hello

I encountered the same issue, and the solution that worked for me was to navigate to the notebook, go to "Lakehouses," select "Remove all lakehouses," and then add the same lakehouse back.

After doing this, the pipeline ran fine for me.
