Extension fails to load in ServerApp #1185

Closed mwouts closed 10 months ago

mwouts commented 10 months ago

When testing the 1.16.0 release candidate (at this commit: https://github.com/mwouts/jupytext/commit/72236220ba8875eddc1fb76c30a98c4b93b5eb32) I see the error below in the Jupyter logs. However everything (the contents manager + the lab extension) still seem to work.

This seems to originate in the renaming of the server extension. Until jupytext==1.15.2 the server extension was part of the jupytext package. On main it is part of jupyterlab_jupytext.
