CodeCov is working on push, but not on PR

[gusye1234]

Hi, my repo is https://github.com/gusye1234/nano-graphrag. CodeCov is working on my pushes on my main branch, but not on any PR from others? Should I configure something else other than CODECOV_TOKEN?

I looked into the PR's action and found it never detect my CODECOV_TOKEN, and so trigger the error

['error'] There was an error running the uploader: Error uploading to https://codecov.io: Error: There was an error fetching the storage URL during POST: 429 - {'detail': ErrorDetail(string='Rate limit reached. Please upload with the Codecov repository upload token to resolve issue. Expected time to availability: 933s.', code='throttled')}
