Description
I’m using bazel 3.5.0 to generate code coverage.dat
files for my C++ build. The coverage.dat
files seem to be in lcov format.
I’m using the bash uploader to upload these files, and it appears to work. However, when I try to view the results in the codecov.io UI, I see a generic message like “There was an error processing coverage reports.”, but it doesn’t tell me what the error was, nor provide any way to debug.
Repository
CI/CD
An internal Google thing called “kokoro”.

Additional Information
This appears to work sometimes. As you can from the commits in this PR https://codecov.io/gh/googleapis/google-cloud-cpp/pull/5070, some of them do process the code coverage info. I’ve no idea why it fails sometimes, and I have no idea how to debug this or where to look for errors.
