poetry.lock file is generated from the pyproject.toml in order to pin versions of all nested dependencies. If pyproject.toml has been changed (or we want to update the unpinned nested dependencies) poetry.lock should be regenerated with

poetry lock --no-update

poetry.lock should be committed alongside pyproject.toml changes.
