Jupyterlab: file saving not possible

Hi renku team,

recently, I get this several times a day. Jupyter lab doesn’t allow me to save and instead tells the following:

Opening the session in another tab until /tree, e.g. https://limited.renku.ch/sessions/lili-2egas-cowdata-a720f5f1/lab/tree solves the problem for some time.

It is not something that really blocks my work but it would be easier without.

Thanks for looking at it.
