The official Codecov Perl library has stopped working today, with reports sent by it to Codecov being rejected with a “Could not satisfy the request Accept header” error.
Ideally, Codecov would continue to accept the “Accept: application/json” header its library is sending, as it used to, but if not I have submitted a pull request to remove the header at Remove Accept header by dracos · Pull Request #42 · codecov/codecov-perl · GitHub which seems to fix the issue. I don’t know if any other client libraries are also affected.
Hope that’s helpful.
