unable to start a notebook session (DIagnostic: fetch_kernel_specs NULL)

anyone seen that before when opening any notebook:

While in the ribbonbar "View" is working all others are not/greyed out suddenly: Home, Edit, Run

 

In addition i get this strange error when trying to start a cell:

 

We are unable to start a notebook session. To re-establish the connection, run the notebook again.
Diagnostic info: (fetch_kernel_specs; gzt5h9) [0] null

  • Hi jochenj 

     

    I didn't get such type of error when am running the notebooks. Just you can logout from fabric and log-in and try ti run again the notebook. If ot worked fine, other wise you can raise a support ticket. How to create a support ticket, pls follow this How to create a Fabric and Power BI Support ticket - Power BI | Microsoft Learn

     

    Please let  me know if it works.

     

     

    Thank you!
