I tried signing the CLA but got this error:

{
  "errors": {
    "github_oauth2_token": "Token permissions have been rejected, please try again"

hi @simonw I pinged the "easycla" people in the cncf slack, I haven't seen the error you referenced before :/

Cla issue seems resolved, thanks. The lint ci issue seems to be on trunk, I’m currently revamping ci/publishing (trustless pypi annd slsa) across the repos in this org, will address this one in next week. Thanks for the contribution.
