jupyter_server 2.0 seems to break showHiddenFiles in JupyterLab

Question

I am using JupyterLab with:

jupyterlab=3.5.1

jupyter_server=1.23.3

and I have the following config:

{
    // File Browser
    // @jupyterlab/filebrowser-extension:browser
    // File Browser settings.
    // *****************************************

    // Show hidden files
    // Whether to show hidden files
    "showHiddenFiles": true
}

as well as:

c.ContentsManager.allow_hidden = True

Everything is working fine and I can see all hidden files in the JupyterLab UI.

Now, if I just update jupyter server to the new version jupyter_server=2.0.1, I don't see anymore the hidden file (the config is the same).

Is there some incompatibility between jupyterlab and jupyter server for the hidden file or the config need to be done in a different way ? It seems that jupyter server is causing some trouble with package like jupytext and other.

I am expecting the following:

Answer 1

Everything was fixed and I am using now the following update tags :

jupyter_server 2.0.5
jupyter-core 5.1.1
(jupyterlab 3.5.2)
