Getting error while running a pipeline

Hi jashfabric 
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. 

You can also try this:
Navigate to the notebook, go to "Lakehouses," select "Remove all lakehouses," and then add the same lakehouse back.

Hope this helps. Please let me know if you have any further questions.
