Need to restart jupyter server frequently

[nileshvd]

Tested in SageMaker JupyterLab

Installed the extension, and kept the tab open. After some time (most likely after some kind of session timeout) S3 browser stopped showing S3 contents. Restarting jupyter server fixes the issue, but this should not be necessary

Expected
No need to restart jupyter server

I think this is caused by session token being generated when the jupyter server starts and that it never gets refreshed. Reference: https://github.com/QuantStack/jupyter-drives/blob/main/jupyter_drives/base.py#L76

For extensions that have a server component like this, a single server restart is required. Are you saying that additional server restarts are needed?

This requires additional server restart, if the app has been running for a long time the auth session times out but the S3Driver still holds the outdated auth session. I observed 500 error response and the UI is empty, user can't even tell whats happening, I created the issue #75 for the UX part of it:

Error

As a solution, at the very least we should try to reload the S3Driver credentials (https://github.com/QuantStack/jupyter-drives/blob/main/jupyter_drives/base.py#L76) if we receive this specific error in the server. Right now we are only doing it once during the initialization.

Closing this as it was fixed by #78, thanks to @gogakoreli!
