KeyError: 'uv-venv-lock-runner' --- can I set runner once for all environments?

[dimaqq]

What I tried to do:

[testenv]
basepython = python3
runner = uv-venv-lock-runner
...

[testenv:unit]
depedency_groups = unit
commands = pytest

The default uvx tox picks up the tox.ini and then fails because one of my deps is missing.

Meanwhile uvx -p 3.10 tox fails with this weird error:
