Enhancement Proposal

This issue was found while working in this PR: #163
It was already opened in microsoft/pyright#9539

They say this is unlikely to be a bug in pyright

However, until version 1.1.381 everything was OK:

✗ tox -re static-charm
static-charm: remove tox env folder /home/jose/trabajos/canonical/repos/cos-proxy-operator/.tox/static-charm
static-charm: install_deps> python -I -m pip install httpcore==0.14.7 pyright==1.1.381 responses==0.20.0 -r /home/jose/trabajos/canonical/repos/cos-proxy-operator/requirements.txt

  congratulations :) (60.61 seconds)

But with 1.1.382+ I see these errors:

✗ tox -e static-charm

WARNING: there is a new pyright version available (v1.1.382 -> v1.1.389).
