Codecov reports are failing to show-up

Example successful upload from our CI: https://github.com/open-telemetry/opentelemetry-go/actions/runs/14112039492/job/39533072036

The corresponding page on the codecov UI: https://app.codecov.io/github/open-telemetry/opentelemetry-go/commit/7376a33e032fffd443e94fa12a82222a7fd3cc72

Investigation is needed to resolve this error. We want our code-base accurately represented in the code coverage UI.

I downloaded the reports from successful and failed uploads.

The failed uploads started to have the following "header":

/home/runner/work/opentelemetry-go/opentelemetry-go/codecov.SHA256SUM.sig
/home/runner/work/opentelemetry-go/opentelemetry-go/codecov
/home/runner/work/opentelemetry-go/opentelemetry-go/coverage-artifacts-~1.24.0/coverage.txt
/home/runner/work/opentelemetry-go/opentelemetry-go/codecov.SHA256SUM

Maybe there was some change in the codecov uploader which the codecov backend does not handle correctly?

Looks like there is already an issue for it:

• [BUG] uploads fail since cli upgraded to v10.3.0 codecov/codecov-action#1801

Example reports:

opentelemetry-go-contrib.txt

opentelemetry-go.txt

The successful opentelemetry-go-contrib report starts with a full repository file listing. The opentelemetry-go one starts with what @pellared mentioned:

/home/runner/work/opentelemetry-go/opentelemetry-go/codecov.SHA256SUM.sig
/home/runner/work/opentelemetry-go/opentelemetry-go/codecov
/home/runner/work/opentelemetry-go/opentelemetry-go/coverage-artifacts-~1.24.0/coverage.txt

contrib is using a job step for the upload:

https://github.com/open-telemetry/opentelemetry-go-contrib/blob/b0c0319eecb7b133f1476c17490e80b2a8d57301/.github/workflows/ci.yml#L88-L93

otel is running it its own job:

https://github.com/open-telemetry/opentelemetry-go-contrib/blob/b0c0319eecb7b133f1476c17490e80b2a8d57301/.github/workflows/ci.yml#L88-L93

This was done to allow the upload to be retried without having to re-run the go coverage tests.
