Hi @Anu1305, we would need more information about your environment to be able to diagnose what may be happening. Could you provide the output of running jupyter --version?

[Anu1305]

Hi Rosio,

Thanks for the response.
After running jupyter --version, I can see this.
jupyter core : 4.6.1
jupyter-notebook : 5.2.2
qtconsole : 4.5.5
ipython : 7.16.1
ipykernel : 5.5.6
jupyter client : 7.1.2
jupyter lab : 1.1.4
nbconvert : 5.6.1
ipywidgets : 7.5.1
nbformat : 5.0.4
traitlets : 4.3.3

[RRosio]

Thank you for providing the additional information @Anu1305. Based on the Notebook version you are using, since it is an older version would it be possible for you to upgrade to Notebook 6.x and check if this error is still coming up?

[RRosio]

Hi @Anu1305, just wanted to follow up with you to find out if you are still encountering this issue, and if so is it possible for you to try to upgrade as previously mentioned?

Hi @Anu1305, closing this issue as there have been no recent updates, however please feel welcome to re-open this issue with updates that could help in diagnosing the error!
