Poetry and nbconvert dependency resolution (ModuleNotFoundError: No module named 'attrs')

[RoelantStegmann]

I use poetry 1.8.3 as my package manager but when I do poetry add nbconvert I have dependencies missing. This makes it impossible to run jupyter nbconvert. This happens for nbconvert 7.16.4 and 6.4.3

If I run pip install nbconvert I get the missing packages (a.o. attrs, bleach, pandocfilters).

Is it a known issue that nbconvert doesn't work well with poetry?
