Is this probably an error from an older version of poetry before poetry became a popular choice for package manager

Kedro does not officially support Poetry yet https://github.com/kedro-org/kedro/issues/1722 some people have managed to make it work but it requires some care. on the other hand, any PEP 621-compliant build backend (setuptools.build_meta, flit-core, pdm-backend) should work

Interesting, I've been using poetry with kedro pretty well for awhile now. Good read here on some of the limitations

yep, it does work - it's just that we don't officially support it yet

Def probably explains a few things Ive had to troubleshoot in the past.
