Render stopped working with this error message:

Warning: The current project could not be installed: No file/folder found for package dmc-docs
If you do not want to install the current project use --no-root.
If you want to use Poetry only for dependency management but not for packaging, you can disable package mode by setting package-mode = false in your pyproject.toml file.
In a future version of Poetry this warning will become an error!

This might be a fix python-poetry/poetry#8662
added --no-root
