unable to format code with yapf

I'm unable to format code with yapf. My setup is using poetry and I use `.style.yapf` file to handle config for yapf. With VS Code format on save functionality, it is not formatting code. Using CLI, it keeps giving me `yapf: toml package is needed for using pyproject.toml as a configuration file` if I use `.style.yapf` and `Invalid TOML file /home/wrench1815/Documents/git/vis-dash/vd-back/pyproject.toml: Unexpected character: 'p' at line 16 col 17` if I use `pyproject.toml` to handle the config.
Also, I tried with `yapf` and `yapf[pyproject]`. With `yapf[pyproject]`, the extra does not install TOML although, as in #964, it is supposed to install it.

Yes, I'm using yapf from my env, I tried using with `poetry run yapf` and `yapf` both. But the errors persist.

If only TOML is manually installed, yapf works unless it won't.
