@mtrezza I suspect the CI error is due to running Codecov directly from ./node_modules/.bin/codecov. To resolve this, I propose migrating to utilize GitHub's Codecov Actions instead. Should I proceed with this update or would you prefer to handle it? If I update the CI actions and add the necessary workflow, would you then add the required token to the repository secrets, or would you rather create a separate PR to handle the entire migration yourself?
