Ok, thanks @ralf.grubenmann and @rrrrrok,
I just removed the “postgresql-wheel” package, as I actually do not need it. And it solved the problem of the failed pipeline. The pipeline passed successfully now.
But, I now get another issue when I open the project :
Build Recommended
JupyterLab build is suggested:
@plotly/dash-jupyterlab needs to be included in build
jupyterlab-dash needs to be included in build
And when I try to click on the “build” button, then I get the following error:
Build failed with 502.
If you are experiencing the build failure after installing an extension (or trying to include previously installed extension after updating JupyterLab) please check the extension repository for new installation instructions as many extensions migrated to the prebuilt extensions system which no longer requires rebuilding JupyterLab (but uses a different installation procedure, typically involving a package manager such as 'pip' or 'conda').
If you specifically intended to install a source extension, please run 'jupyter lab build' on the server for full output.
I then searched on the forum and found this Dash app with jupyter-server-proxy - #17 by tolevski but in my case werkzeug is already downgraded to 2.2.1.
Concerning the rest I read through on the post Dash app with jupyter-server-proxy - #23 by rrrrrok, I am not sure what I should try to solve it.
A consequence is that I don’t see anymore the git user-friendly interface (I can only commit through the terminal).
